What You Can Do With AutoCAD Map 3D2008

AutoCAD Map 3D is the leading engineering GIS platform for creating andmanaging spatial data. AutoCAD Map 3D bridges CAD and GIS by providingdirect access to data, regardless of how it is stored, and by enabling the use ofAutoCAD® tools for maintaining a broad variety of geospatial information.Using Open Source FDO Data Access Technology, AutoCAD Map 3D nativelyaccesses spatial data stored in relational databases, files, and Web-based services,providing easy management of large geospatial data sets while streamliningentire workflows.

The topics in this section describe what you can accomplish with AutoCADMap 3D.

Combine map objects

The Autodesk Feature Data Objects (FDO) Data Access Technology helps youwork seamlessly on a variety of spatial and nonspatial databases and fileformats natively, without the need for translation and risk of data loss. Thesedata sources may contain a single feature type, such as parcel or streetcenterline, or may contain a complex data model with multiple features andattribute tables. AutoCAD Map 3D automatically resolves differences in scaleand coordinate systems.

Add items such as the following:

■ AutoCAD drawing objects

■ Spatial features stored in a relational database, such as Microsoft® SQLServer, Oracle® Spatial, and MySQL

■ Features stored in a spatial data file format, such as an ESRI® SHP orAutodesk® SDF file

■ Features stored in middleware, such as ESRI® ArcSDE®

■ Raster images, including DEM surfaces that show elevation

■ Web-based images from WFS and WMS

■ Attribute or point data stored in a spreadsheet or database that can belinked to drawing objects

2 | Chapter 1 Introducing AutoCAD Map 3D 2008

■ Data from third-party providers, leveraging the power of Open Source

Add spatial data by dragging and dropping file-based sources into your map,or use the Data Connect window to connect to any non-DWG data sourceand add the feature classes you want.

Add objects from AutoCAD drawings using a variety of techniques:

■ Use data-based queries to add objects from a drawing (find all objects ona particular layer, all objects of a certain size, all objects with certainproperties).

■ Define areas to add (draw a selection window).

■ Add drawing layers.

Create and edit map objects

Use several methods to create and edit objects:

■ Use the full set of AutoCAD editing tools and commands to add or changemap objects from different object sources without converting the data.

■ Update original data stores with your changes automatically, or workoffline and update when you finish.

■ Edit attribute data values for objects. The changes are reflected in theoriginal data source.

Use map-related data

Use attribute data as the basis of queries and display it as text in your map:

■ Import attribute data.

■ Import objects with links to external data.

■ Link database entries to the data already associated with drawing objects.

■ Join an attribute data store to an existing feature class.

■ Create and manage attribute data within AutoCAD Map 3D using DataTable and Data View.

Create and edit map objects | 3

■ Display attribute data on your map as text.

■ Examine and publish map metadata.

Format map objects

Change the way objects in the map appear, without changing the objectsthemselves:

■ Assign visual properties to object groups, or to objects that match certaincriteria.

■ Use themes to vary visual properties based on attribute values.

■ Save display layer definitions (which include styling information andpointers to the data source) for re-use.

■ Use special formatting options for raster images to show hillshade, contours,and more.

Manage map data

Manage the structure of data and move data from one format to another:

■ Use Schema Editor to create new schemas

■ Add and delete features and properties in existing schemas.

■ Use Data Connect to create a new data store from within AutoCAD Map3D.

■ Use Bulk Copy to copy data from one data store to another.

■ Export DWG data to a variety of spatial data formats, including Oracle,SDF, and SHP.

■ Export your entire map to DWG format.


Perform analysis on maps

Use various methods to analyze data:

■ Sort, filter, and edit information about map items in a tabular format.

■ Locate specific coordinate points and measure the geodetic distancebetween points.

■ Visually communicate relative values and scale with themed displays.

■ Temporarily join data from external data stores to features in your mapand use that data to theme the features.

■ Create contour maps to help you analyze 3D terrain.

■ Use raster-based theming to analyze elevation, slope, and aspect, drapemap data over surfaces and view the data in 3D, and more.

■ Create buffer zones based on feature properties and select objects basedon their proximity to a buffer. Save the buffer as its own feature class, forfuture re-use.

Publish maps

In addition to printing your maps on a plotter, you can create or do thefollowing:

■ Map books divide a large map into tiles, which are rendered on separatepages. You can include a legend, title, and other information on each page.

■ Maps with insets can be produced using map books.

■ Reports create comma-separated text files listing information about objectsin attached drawing files. You can import the report files into a spreadsheet,database, or document.

■ Autodesk MapGuide® technology allows you to post maps and map bookson the Internet or an intranet. The way that you send maps to this platformvaries, depending on whether you use Autodesk MapGuide 2007, MapGuideOpen Source, or Autodesk MapGuide versions 6.5 and earlier.

■ Autodesk DWF is a Web-based format that allows your maps to be displayedin Autodesk Design Review (the latest version of the DWF Viewer), and

Perform analysis on maps | 5

distributed or posted on on the Internet or an intranet. You can createmap books in a DWF format.As long as you have assigned a coordinate system to all the maps in yourDWF file, the publishing operation will automatically convert thecoordinate information to latitude/longitude coordinates. Autodesk DesignReview 2008 can automatically navigate to a specific location when youenter coordinates, and displays coordinates of any location in the mapwhen you move your mouse over that location. When your computer isintegrated with a GPS device that uses the NMEA 0183 protocol, fieldworkers can center the map to the coordinates provided by the integratedGPS device on your system, and display the “my coordinates” icon withinthe map.

■ Create a static Web page from your map.

■ Package all dependent files for a map for transmittal to another AutoCADMap 3D user.

Basic Product ConceptsYou must understand the following concepts before you begin using AutoCADMap 3D. If you are an experienced AutoCAD user, some of these conceptsmay be familiar to you.

Maps and map files

A map file connects to all the sources for your map: spatial features, drawingobjects, raster images, and attribute data. Each map file can contain multipledisplay maps (for printing or for online distribution), in which you canselectively hide or show items in your map, and you can apply styles to thoseitems, based on data, layers, and other criteria. Changes that you make to theappearance of items in a map do not affect those items in your map file.

Source files and map files

One map can use multiple sources. For example, you might attach a DWGfile to your map and query in one or two of its layers. Then, you might connectto a SHP file that becomes another layer in your display map, or add featuresfrom a spatial database. These become part of your map.


The relationship between the sources and the map is dynamic. When youchange the objects in your map, you can save those changes back to theiroriginal source files or databases. You can set an option so this happensautomatically, or you can work offline and update the feature source whenyou finish editing. Check out a feature to lock it for other users (if the featuresource supports this) and check it back in to make it available again.

DWG files and features

Objects in maps fall mainly into two categories: drawing objects and spatialfeatures (FDO). Drawing objects come from AutoCAD drawings and spatialfeatures from a centralized data store (like an Oracle database) or a spatial datafile (like a SHP or SDF file).

Some AutoCAD Map 3D functions are more useful for one object type thanfor another. For example, the drawing cleanup feature eliminates extraneouslines in DWG files, but drawing cleanup does not work on an FDO feature.

Some functions use different commands, depending on the object type. Thefollowing table explains the functions available for the two data types:

Importing/exporting data and connecting to datastores

When you add data to your map (a spatial feature, a DWG object, or attributeinformation), the link to that data is "live." If you are connected to the datastore and it is updated, the related item in your map is also updated. If youchange the data in your map, you can update the data in the data store.

However, when you import data you get a "snapshot" of the data at the timeyou import it. If the data changes after that, you will not see any changes inyour map unless you import the data again. There is no way to update importeddata in its source. Similarly, when you export data, you export the currentdata only. The connection to the live data is lost.

Getting Ready to Use the TutorialsThese AutoCAD Map 3D tutorials cover the following:

■ Getting started (page 20): Take a quick tour of the application. Create anew map file, assign a coordinate system, connect to data, style features,and save your work.

■ Building a map (page 29): Learn all the basics of creating a map from startto finish. Use multiple sources, design themes and composite styles to

Importing/exporting data and connecting to data stores | 9

change the appearance of objects, create new features and edit them, andpublish your finished map.

■ Analyzing Data Using Styles, Joins, and Buffers (page 67): Add a surfaceand style it using a theme and contour lines to show elevation. Join anexternal database to a feature and create a stule usng both sets of data.Create a buffer zone that highlights areas within 1000 feet of a river andidentify parcels that lie within that zone. Export comma-separated datafor use in a report to the owners of those parcels.

■ Managing Data From Different Sources (page 97): Export DWG data toAutodesk SDF format, and then connect to the resulting SDF file to add itas a layer in another map. Use Bulk Copy to copy the SDF data to SHPformat. Import the SDF data to convert it back to DWG layers.

Preparing your sample data

When you installed Autodesk Map 3D, the tutorial sample data was installedon your computer in the \Program Files\Autodesk Map 3D 2007\Help\Map 3DTutorials folder. You will need that sample data to use the tutorials. Copy theMap 3D Tutorials folder to My Documents.

About This TutorialThe lessons in this tutorial take you through the entire workflow of buildingand publishing a map. You will use real data from the city of Redding,California. As you work through the tutorial, you will do the following:

■ Start a map project by connecting to all the data stores needed by yourmap. Data stores can include spatial databases, spatial data files, such asShape (SHP) and SDF files, AutoCAD drawings (DWG files), and rasterimages. Connecting to a data store makes the information in that datastore available to your map.

■ Style the objects in your map so you can easily identify them. Styles canhelp you provide complex information quickly and intuitively. For example,themed styles can show population density, water depth, or the relativeheight of geographic features.

■ Edit objects in your map. In AutoCAD Map 3D, you can check out andedit any type of object—geometry in a DWG file, a schema in a Shape file,or spatial data stored in an Oracle database—using AutoCAD commands.You can then save the changes back into their original format. You canalso use the Data Table to change the properties of spatial data.

■ Publish the resulting map for display on a Website. In this tutorial, youpublish to DWF format (for use with Autodesk Design Review). You canalso publish or export to Autodesk MapGuide, save your map as a staticWeb page, or package all the files needed to edit the file and transmit themto another AutoCAD Map 3D user.

Lesson 1: Use Multiple SourcesIn the first set of lessons, you practice connecting to data from a variety ofsources.

Exercise 1: Drag and drop a source file

Start by creating a new map file and adding the city boundaries of Reddingto it.

30 | Chapter 2 Tutorial: Building a Map

To create a map and add a source file

1 If you have not already done so, copy the \Program Files\AutoCAD Map3D 2008\Help\Map 3D Tutorials folder to My Documents.

2 Create a new map file.

■ Click File menu ➤ New.

■ Select the map2d.dwt template.

■ Click Open.

3 Set the coordinate system for the map.

■ Switch to Map Explorer (page 124) in the Task Pane (page 126).

■ Right-click Current Drawing and click Coordinate System.

■ Enter CA-I and click OK.

NOTE This field is case-sensitive. Enter uppercase CA, a hyphen, anduppercase letter I.

4 Add the city boundaries to your map by dragging and dropping a sourcefile to Display Manager.

■ Switch to Display Manager (page 122) in the Task Pane.

■ Use Windows Explorer to navigate to the folder in My Documentswhere you copied the sample files.

■ Resize the AutoCAD Map 3D window and your sample data folderwindow so you can see both of them at the same time.

■ Drag and drop the City_Boundary.sdf file onto the lower area of theDisplay Manager, just above the Map Base layer.

Exercise 1: Drag and drop a source file | 31

Drag and drop the city boundary file to Display Manager

The Redding city boundaries appear in your map.

To continue this tutorial, go to Exercise 2: Attach a drawing file (page 32).

Exercise 2:Attach a drawing file

You can use Display Manager to attach an AutoCAD drawing file.

NOTE This exercise uses the map you created with the map2d.dwt template, withthe modifications you made in the previous exercise.

To attach a DWG file


2 Switch to Display Manager in the Task Pane.

3 Click Data ➤ Add Drawing Data ➤ Attach Source Drawings.


Use Display Manager to attach a drawing file

4 Click Attach.

5 Navigate to the folder in My Documents where you copied the sample filesand select Counties.dwg. Click Add and then click OK.

6 Click OK to attach the drawing file to your map.

When you attach a drawing, it is not listed in Display Manager (page 122)and it does not appear in your map. You must “query in” objects fromthe drawing to use in your map.

To continue this tutorial, go to Exercise 3: Query in data from the drawing(page 33).

Exercise 3: Query in data from the drawing

The drawing file you attached is a map of California with polygons definedfor each county. Since the city of Redding is in Shasta County, you will addthe Shasta County boundaries to your map. You can query in data based onlocation, properties, or data. In this case, query by the name of the county,which is stored as object data.

Exercise 3: Query in data from the drawing | 33

NOTE This exercise uses the map you created with the map2d.dwt template, withthe modifications you made in the previous exercises.

To query in drawing data

1 In Display Manager (page 122), click Data ➤ Add Drawing Data ➤ QuerySource Drawing.

2 In the Define Query Of Attached Drawings dialog box, under Query Type,click Data.

3 In the Data Condition window, select the Object Data option.

4 Leave the Tables setting as it is and select NAME in the Object Data Fieldslist.

5 Leave Operator set to = . For Value, enter Shasta.

Define the data condition for the query

The query is case-sensitive. Be sure to enter it as shown.

6 Click OK in the Data Condition window, and then click OK again toexecute the query.


7 Click View menu ➤ Extents.

The Shasta county boundaries are now displayed in the map, and anAttached Drawing Element layer is displayed in Display Manager.

NOTE You may see an alert as you work through the remainder of the tutorial,warning you that the association between queried objects in the current andattached drawings will not be retained once the current drawing file is closed.This message reminds you to save back any changes you make to the originaldrawing file. Since you will not edit the Shasta County drawing in this tutorial,you can safely ignore the alert.

To continue this tutorial, go to Exercise 4: Use Data Connect (page 35).

Exercise 4: Use Data Connect

Use Data Connect (page 121) to connect your map to a file containing parceldata.

Use the Data Connect window to attach any non-DWG data source: databaseformats, such as ArcSDE, Oracle, or SQL Server; an ODBC source, such asMicrosoft Access; a raster file; Web-based sources such as WMS or WFS; orspatial data files, such as SDF and SHP.

Data Connect displays information about all attached non-DWG data sources,even if you didn’t use Data Connect to attach them. For example, the SDF fileyou dragged and dropped into your map is listed on the left.


To use Data Connect


2 In Display Manager (page 122), click Data ➤ Connect to Data.

3 Under Data Connections By Provider, select Add SDF Connection.

4 Click the file icon next to Source File.

5 Navigate to the folder in My Documents where you copied the sample filesand select Parcels.sdf. Click Open.

Exercise 4: Use Data Connect | 35

6 Click Connect to add the parcel data file as a data source.

7 Under Add Data To Map, select Parcels and click Add To Map.

In the Data Connect window, connect to a data provider and then select the featureclass you want.

The coordinate system for this feature class is displayed next to its name.If this information was incorrect, you could click the current coordinatesystem listing to see a down arrow and select a different coordinate system.

NOTE Do this only if you know the original coordinate system for thefeature—do not change the coordinate system to match your map. AutoCADMap 3D converts each feature from its own coordinate system into yourcurrent map’s coordinate system automatically. If you change the coordinatesystem, the conversion may not be correct.

When you click Add To Map, a layer called Parcels is displayed in the listin the Display Manager (page 122). A layer can be styled, saved, displayed,or hidden, independent of other layers in your map.

To continue this tutorial, go to Exercise 5: Add a raster image (page 37).


Exercise 5:Add a raster image

Bring in an aerial photograph to display behind the objects in your map.Real-world elements in the photograph line up with the geometry in yourmap and make it easier for the viewer to get a visual orientation.


To add a raster image


2 The Data Connect (page 121) window should still be displayed. If it is not,open Display Manager (page 122). Click Data ➤ Connect To Data.

3 Under Data Connections By Provider, choose Add Raster Image Or SurfaceConnection.

4 Click the folder button next to Source File Or Folder.

5 Navigate to the folder in My Documents where you copied the samplefiles, find the folder containing the JPEG 2000 raster files (originally calledJP2K), and select it. Click OK.

6 Click Connect to add the folder as a data source.

7 Under Add Data To Map, select the images you want.

The folder contains multiple JPEG 2000 files, each of which covers a smallarea of the city of Redding. Select the j-05, j-07, l-05, and l-07 items.

Exercise 5:Add a raster image | 37

If your folder contains multiple images, select the ones you want.

8 Set the coordinate systems for the images.

■ Click Edit Coordinate Systems.

■ Click in the blank field in the row labeled “Default.”

■ For Category, choose USA, California.

■ Under Coordinate Systems In Category, click CA-I.

■ Click OK in both dialog boxes, until you return to the Data Connectwindow. All the images now show CA-I as their coordinate systems.

9 Select Combine into one layer, so you can style the raster images as asingle item in Display Manager. Enter a name for the layer.

10 Click Add To Map.

To see the results

1 Close the Data Connect window.


2 Right-click the new raster layer and click Zoom To Extents.

To continue this tutorial, go to Exercise 6: Display the raster image behindother features (page 39).

Exercise 6: Display the raster image behind otherfeatures

You want the raster image to provide context for the parcels in your map, butright now it is hiding the parcels. Move the raster behind the parcels and makethe parcels semi-transparent so you can see the raster image.


To display the raster image behind other features

1 Make sure the fourth item in the Display Manager (page 122) menu barreads Draw Order. If it reads Groups, click it and change it to Draw Order.

2 Drag the new raster layer just below the Parcels layer.

The list of layers is the draw order for your map. The item at the top ofthe list is also at the top of the map’s Z-order. Dragging the raster imagebelow the Parcels layer places it behind that layer in your map.

To see the raster layer behind the parcels, make the city boundary layerwhite and make the parcels semi-transparent.

3 Select the City_Boundary layer in Display Manager.

4 Click Style to see the Style Editor.

NOTE If the Style Editor is docked, move your cursor over it to display it. Itmay be docked at the left side of the application window.

5 In the Polygon Style For 0 - Infinity: Scale Range section of the StyleEditor, click the Style entry.

Exercise 6: Display the raster image behind other features | 39

6 Change the Foreground Color to white and click OK.

7 Select the Parcels layer in Display Manager. In the Style Editor, click theStyle entry again.

8 Move the Foreground Transparency slider to 50% and click OK.

Close the Style Editor. Right-click the Parcels layer and click Zoom ToExtents to see the results.

9 Save your map.

Where you are now

You have assembled all the raw materials for your map. The aerial photographprovides context. The geometry from the DWG drawing shows the countyboundaries, and the SDF files add the city boundary and parcel outlines.

Lesson 2: Style Map FeaturesIn the Getting Started lesson, you changed the style for the roads in your mapby changing the color, thickness, and pattern for the lines representing roads.

In this lesson, you use themed styles to give the viewer an immediate senseof the value of each parcel.

Exercise 1: Create a theme for the parcels layer

A theme uses a range of colors to represent an analogous range of values. Youcan also use theming to show relative area, population density, water depth,or height of geographic features.

NOTE This exercise uses the map you created with the map2d.dwt template, withthe modifications you made in the previous lesson (page 30).

To style the parcels layer with a theme

1 To open your finished map from the previous lesson, click File ➤ Open.

2 Locate your map.

3 Select it, and click Open.


4 Create a theme for the parcel layer.

A theme is a display style. Styles for spatial features are assigned by layer.

5 Select the Parcels layer in Display Manager (page 122) and click Style.


6 Under Polygon Style For 0 - Infinity Scale Range, click New Theme.

Click New Theme to define a theme for the Parcels layer

To continue this tutorial, go to Exercise 2: Define the theme (page 41).

Exercise 2: Define the theme

Tie the theme definition to the value of the parcels: lighter colors will representparcels with lower values and darker colors will represent parcels with highervalues. The parcel value is the "condition" used to determine the color of theparcel in the map.


Exercise 2: Define the theme | 41

Use the Theme Polygons dialog box to design your theme

To define the theme

1 Under Create Thematic Rules Based On A Property, click the down arrownext to Property and select LAND_VALUE. Leave the minimum value,maximum value, and distribution settings as they are.

2 Under Theme The Polygons, click the button labeled "…" next to theillustration of the Style Range.

3 Set Foreground transparency to 50% so you can continue to see the rasterimage below the parcels.

4 Select colors from the color boxes under From and To for Foregroundcolor.

5 Experiment with line thickness and color, if you like.


Set transparency, colors, and line attributes for the theme

6 Click OK to return to the Theme Polygons window.

To continue this tutorial, go to Exercise 3: Add labels (page 43).

Exercise 3:Add labels

Add a label for each parcel, based on its land value.


Exercise 3:Add labels | 43

To add labels

1 Select Create Feature Labels and click the button labeled "…" next to thepicture of the Label Ramp.

Select the property whose data will be displayed in the labels

2 For Property To Display, choose LAND_VALUE. Leave the other settingsat their current values for now.

3 Click OK to close the Style Label window. Click OK again to apply thetheme to your map.

4 Close the Style Editor so you can see your map again.


5 Zoom in so you can see the labels.

■ Double-click the box labeled Scale 1: at the bottom of the applicationwindow.

■ Enter 10000 in the field labeled Enter Scale Value and click OK.

Use the Scale field to see the style at different zoomlevels

6 Save your map.

Where you are now

Themed parcels with labels

In the map, the parcels are colored to represent their relative values, whichare displayed as labels on each parcel.

Exercise 3:Add labels | 45

Lesson 3: Change the Display by Zoom LevelUse styles to make objects display differently, depending on the viewer's zoomlevel. In this example, when the viewer is zoomed, in roads are dark gray witha dashed yellow centerline. When the viewer zooms out, the roads display assolid black. When the viewer zooms out far enough, roads are not displayedat all.

Exercise 1:Add roads to your map

Add roads to your map and assign several styles to them, with each styledisplaying at a different zoom level.

NOTE You may need to scroll the Data Table to the left to see the Selectfields.

AutoCAD Map 3D scrolls to the selected parcel and displays it to the rightof the Data Table.

5 Make a note of the number in the Select field, because you will need touse it again later.

6 Close the Data Table.

NOTE You can do a more sophisticated search by clicking Edit menu ➤ Search. That option lets you query a layer with a Boolean condition—forexample, ACRES > 1 to find parcels that are larger than an acre. The mapthen shows only the objects that match your query.

7 Save your map.

Where you are now

You used the Data Table to zoom to a parcel.

Lesson 6: Edit ObjectsEdit objects and then update their original data stores.

Exercise 1: Check out and edit a feature

If AutoCAD Map 3D is set to check in your changes automatically, the sourcefile will update while you edit. The safest way to edit spatial data is to turnoff this automatic update feature, check out the item, and then edit it. Onceyou make your changes, check the feature back in to update it with yourchanges and make it available to others again.


When you check out a feature, that feature is locked for editing by anyoneelse (if the data format supports such locking). Other people can view thefeature source, but they cannot change it until you check it back in.

Where you are now

You removed the reference to the Map Base layer from the legend, and thelegend now reflects the new organizational order.

Lesson 8: Publish Your MapPublish a georeferenced map in DWF format, for eventual display on the Webor on an intranet. DWF (Design Web Format™) is an open, secure file formatdeveloped by Autodesk for sharing engineering design data. DWF files arehighly compressed, so they are smaller and quickly transmitted and viewed.

Lesson 8: Publish Your Map | 61

This format can include attribute data, as well as the graphical elements ofyour map.

As long as you have assigned a coordinate system to all the maps in your DWFfile, the publishing operation will automatically convert the coordinateinformation to latitude/longitude coordinates. Autodesk Design Review 2008can automatically navigate to a specific location when you enter coordinates,and displays coordinates of any location in the map when you move yourmouse over that location. When your computer is integrated with a GPS devicethat uses the NMEA 0183 protocol, field workers can center the map to thecoordinates provided by the integrated GPS device on your system, and displaythe “my coordinates” icon within the map.

Files in DWF format can be displayed using Autodesk® Design Review. Forproduct information and a download link for this product, refer to theAutodesk Design Review page on the Autodesk Website. Autodesk DesignReview is the latest version of the Autodesk® DWF Viewer, and includes theability to measure, markup, stamp, review, convert, and aggregate DWFcontent.

Exercise 1: Specify attributes to include

About the Analyzing TutorialUse AutoCAD Map 3D to analyze data in many ways. This tutorial demonstratesthree of them:

■ Analyze data visually, using surfaces.Connect to a surface (DEM) image and style it using a theme to showrelative elevation. Then, connect to a file that shows parcel informationand make the parcels semi-transparent so you can see the raster imagebelow them. The elevation theme of the raster helps you see the elevationof the parcels.

■ Analyze data with external information sources, using joins.Join a Microsoft Access database to the parcels layer in the map to seeinformation about the parcel owners. Using joins, you combine data sourcestemporarily, without altering the original data stores. Use the combineddata as though it were a single data source—for example, style a layer basedon its joined data, even though the joined data is not part of the originallayer data store.

■ Analyze data by proximity, using buffers.Create a buffer around the river in Redding to see which parcels lie withinthe flood zone. Select the parcels that adjoin the buffer and save themseparately so you can notify their owners in case of a flood, using the ownerinformation you joined to the parcels.

Export relevant data to a comma-separated file that you can import intoMicrosoft Excel or Access. Use that data to create a report to send to theowners.

Lesson 1:Analyzing Data Visually, UsingSurfaces

Use the Data Connect window to connect to a DEM file and style it to showthe elevation information it contains.

Exercise 1: Prepare your map file

Create a new map file and assign a coordinate system. Color the mapbackground white so you can better distinguish features, such as rivers, which

The styled surface helps you evaluate parcel elevation

Lesson 2:Analyzing Data With ExternalInformation Using Joins

Join the parcels layer to a Microsoft Access database that contains ownerinformation.

To connect to an Access database from AutoCAD Map 3D, you must first setup an ODBC connection for that database using a control panel in Windows.Then, connect to this source using Data Connect, just as you connected tothe physical data sources in your map. The database source contains a fieldthat you can match to a field in the Parcels layer, so you can join the data tothe parcels and style or analyze all the resulting data seamlessly.

Lesson 2:Analyzing Data With External Information Using Joins | 81

Exercise 1: Set up an ODBC connection for anAccess database

Set up an ODBC connection for the Access database using the AdministrativeTools control panel in Windows.

Lesson 3:Analyzing Data by Proximity UsingBuffers

Create a buffer that specifies an area within 1000 feet of the river and use itto determine which parcels lie within the river's flood zone.

Compare the two sets of parcels—the complete set of Redding parcels andthose that lie within the flood zone—by attaching both SDF data sources toyour map as separate layers and styling them differently.


Exercise 1: Create a buffer representing the floodzone based on the river

Start by creating the buffer.

To create the buffer

1 Clear the check boxes next to the surface and contour layers in DisplayManager to hide those layers and more easily see the rest of the process.

2 Click Analyze menu ➤ Buffer.

3 Set the buffer distance to 1000 feet and click Merge All Buffers.

4 Click Select Features.

5 Click the river in your map.

About the Managing Data TutorialAdd data to your AutoCAD Map 3D maps from both DWG files and fromgeospatial data sources, such as Oracle database stores or SDF files. You canalso move data from one of these data formats to another, for example, toaccomplish the following:

■ Make DWG data available in a geospatial format for other organizations.

■ Move your own organization's data into a geospatial environment.

■ Bring geospatial data into a drawing file.

■ Let people without access to AutoCAD Map 3D make changes to map data.

Choose the appropriate option to move data into or out of a map:

■ When you add DWG data to your map, you attach the drawing to yourmap and then query in the objects you want to use. If you change thoseobjects, you can either update the original drawing or not.

■ When you connect to geospatial (FDO) data, you can maintain a liveconnection to the data, or you can work offline and update your data storewhen you finish.

■ When you import data into your map, you insert a "snapshot" of that data.Use this option when you don’t want to affect the original data store, andyou don’t want changes in that data store to change your map. You canimport from a variety of geospatial sources. When you use the importoption, the imported material is added to your map as DWG data.

■ When you export data, you export only DWG objects—no geospatialfeatures are exported. However, you can save your map to AutoCAD DWGformat and then export it.

■ To move geospatial data to another format, you can either use Bulk Copyor you can save individual layers to the Autodesk SDF format. To moveDWG data to another format, export it to SDF, SHP, or Oracle, and thenuse Bulk Copy to move it to other formats.

In this tutorial, you will export DWG layers to new SDF files, so that theybecome geospatial data. After adding the SDF files to a map as display layersand adding aproperty to the SDF schema, you will use Bulk Copy to convertthe SDF data to SHP format. Finally, you will import the SDF files into a map

as DWG objects, making a round-trip journey from DWG to SDF and backagain.

Lesson 1: Exporting DWG Data to SDFOpen a sample map that contains several DWG layers. Export the drawinglayers to a new SDF file, creating your feature classes based on layers. TheDWG objects become geospatial data when you export them to SDF.

Exercise 1: Export drawing layers to SDF

Open a sample map containing drawing layers and export those layers to anSDF file.

Lesson 1: Exporting DWG Data to SDF | 99

To open the map file

1 If you have not already done so, copy the sample files for the tutorialsto a directory on your hard drive.

2 Start AutoCAD Map 3D and open the sample map called DWGMap.dwg.

The DWGMap.dwg file contains three drawing layers


3 Click Setup menu ➤ AutoCAD Layers to see the drawing layerinformation.

You cannot maintain styling information when you export drawingobjects to SDF, but you can include object attributes. When you exportthese layers, you will include the general object attributes, such as colorand line weight, so you can reconstruct the styling later if you wish.

Style drawing layers in the Layer Properties Manager. Style Display Manager layers inthe Style Editor.

4 Close the Layer Properties Manager.

To export the layers to SDF

1 Click File menu ➤ Export ➤ As SDF.

Exercise 1: Export drawing layers to SDF | 103

7 Click OK when you finish examining the feature class names.

8 Click OK in the Export dialog box to export the data.

Where you are now

You exported DWG layers to Autodesk SDF format.


Lesson 2: Using the Resulting SDF FilesConnect to the SDF file you created and edit the objects in the map asgeospatial features. (If you imported the SDF file instead of connecting to it,the data would come back in as drawing objects instead of geospatial data.)

NOTE This exercise uses a new map you create with the map2d.dwt template.

Exercise 1: Create a new map

Create a new map file.


1 Close the current map.

2 Create a new map using the map2d.dwt template.



■ Right-click the Current Drawing entry and click Coordinate System.


Set the coordinate system for a new mapfrom Map Explorer

Lesson 2: Using the Resulting SDF Files | 105

To continue this tutorial, go to Exercise 2: Connect to the New SDF Data (page106).

Exercise 2: Connect to the New SDF Data

Connect to the SDF file you created.

NOTE This exercise uses the map you created in the previous exercise, and theSDF file you saved in Lesson 1: Exporting DWG Data to SDF (page 99).

To connect to the new SDF file


Switch to Display Manager to connect todata

2 Under Data Connections By Provider, click Add SDF Connection.

3 Click the file button next to the Source field under Add A NewConnection.

4 Navigate to the SDF file you created and click Select.


Connect to the SDF file you just created

Each layer from your original map is listed as a separate feature class,including the base layer (layer 0).

6 Select all the feature classes except the one named "0."

Exercise 2: Connect to the New SDF Data | 107

Check all the feature classes except the one labeled “0”

7 Click Add To Map.


To continue this tutorial, go to Exercise 3: Examine the layer properties (page108).

Exercise 3: Examine the layer properties

Each feature class from the SDF file is now a feature layer in Display Manager.These layers are geospatial, so you can use some of the AutoCAD Map 3Dfeature options to edit them. Examine the attributes of a layer in the DataTable (geospatial features do not appear in the Layer Properties Manager—itis just for drawing objects). Add a new property to a feature using the SchemaEditor.

NOTE This exercise uses the map you created in the previous exercises.


To examine the properties of a layer

1 Select the Roads layer in Display Manager and click Table.

NOTE In this example, the Data Table was undocked by dragging it awayfrom the edge of the window.

All attributes of the Roads feature appear in the Data Table

If you had assigned other attributes to this drawing layer in your originalmap, they would be displayed here.


To continue this tutorial, go to Exercise 4: Use Schema Editor to add properties(page 110).

Exercise 3: Examine the layer properties | 109

Exercise 4: Use Schema Editor to add properties

The set of feature classes and their properties is called a schema. The schemacan specify constraints that determine which objects you can add to a particularfeature class. For example, to add an object to the Roads feature class, thatobject might need to be a line. Properties are like attributes—they arecharacteristics of all objects in the feature class. For example, a Roads featureclass property might specify the number of lanes it has, or its speed limit.

You cannot change the schemas for all data source types, but you can edit theschemas for SDF files. In this lesson, edit an SDF schema to add a property tothe Roads feature class.

NOTE This exercise uses the map you created and modified in the previousexercises.

To add a property to the Roads feature class

1 Switch the Task Pane to Map Explorer.

2 Select the SDF data source at the top of the pane.

3 Click Schema ➤ Edit Schema.

In Map Explorer, select the schemato edit and then choose Edit Schema

4 In the Schema Editor, expand the tree on the right side of the windowand select Roads.

5 Click New Property at the top of the window.


A new property appears on the left, under the existing properties.

6 Specify the characteristics of the new property using the informationshown below:

Create a new property with these values

This creates a property that represents the number of lanes for a road.The value must be a whole number between 1 and 5. There is no defaultvalue for this property.

7 Click Apply.

The "Property1" entry on the left is updated to show the new name.

8 Click OK and close the Schema Editor.

To populate the new properties with data

1 Select the Roads entry in Map Explorer and click Table.

Exercise 4: Use Schema Editor to add properties | 111

2 In the Data Table, scroll all the way to the right to see the new property.

3 Enter the number of lanes for a few roads.

If you enter a value that is outside the allowable range, a warning iconis displayed.

The yellow warning triangle alerts you that a value of 7 is out of range for thisproperty.


Where you are now

You connected to the SDF file you created earlier and added a new propertyto its schema. You entered values for the new property in the Data Table.


Lesson 3: Moving SDF Data to a DifferentGeospatial Format

Use Bulk Copy to move the Roads data in your map from the SDF format itcurrently uses, to SHP format. The information will be stored in a set of newSHP files in a folder that you create. The layers in your map are geospatialfeatures, so you can use Bulk Copy to move the data to any other geospatialdata format.


Exercise 1: Connect to a new SHP file folder

Create a new, empty folder to contain the SHP files.

To create the folder

1 Use Windows Explorer to navigate to the location where you copied yoursample tutorial files.

2 Create a folder for the SHP files.

3 In AutoCAD Map 3D, switch the Task Pane to Display Manager.

4 Choose Data ➤ Connect To Data.

5 Click Add SHP Connection on the left side of the Data Connect window.

6 On the right side of the Data Connect window, click the folder icon (notthe file icon) and select the folder you just created.

Lesson 3: Moving SDF Data to a Different Geospatial Format | 113

Connect to the SHP folder you created

Click Connect and close the Data Connect window without addinganything to your map.

To continue this tutorial, go to Exercise 2: Use Bulk Copy to move an SDFlayer to SHP format (page 114).

Exercise 2: Use Bulk Copy to move an SDF layer toSHP format

Copy the Roads layer from SDF format to SHP format using the Bulk Copyfeature.



To copy the Roads layer to SHP format

1 Select the SDF_1 schema in Map Explorer.

2 Click Tools ➤ Bulk Copy.

8 On the Continue Bulk Copy message, click Continue Bulk Copy.

The data from the SDF Roads layer is copied to the new SHP file.

9 Click OK on the Bulk Copy Results message and close the Bulk Copydialog box.

Where you are now

You copied the data from your SDF layers to SHP format.

Lesson 4: Importing SDF Files as DWG LayersImport the geospatial data back into a map as DWG data.

You moved some DWG data to SDF format and from there to SHP format, soyou can distribute it to people who use geospatial data.


You may need to move the data back into DWG format. For example, if otherpeople change the data, you can re-import it so you have the latest version.When you import SHP or SDF files, they are added to your map as drawingobjects, not as geospatial data. You can use that feature to complete theroundtrip journey of the data back into DWG format.

NOTE This exercise uses a new map you create with the map2d.dwt template.

Exercise 1: Prepare your map file

style Settings that specify how to display the objects in a Display Manager(page 122) layer. For example, you can style color, linetype, linewidth, andscale.

surface layer A layer in Display Manager (page 122) containing feature (page123)s from a raster (page 125) image that contains elevation information. Surfacelayers are added to your map using Data Connect. See also See also AutoCADlayer (page 121), drawing layer (page 122), feature layer (page 123).

table A set of data arranged in records (rows) and fields (columns). When atable is displayed in a grid, records are displayed in horizontal rows and fieldsare displayed in vertical columns. Each field value in the table is displayed ina cell.

Task Pane AutoCAD Map 3D window that displays information about thecurrent drawing. The Task Pane contains three tabs: Map Explorer (page 124),Display Manager (page 122), and map book (page 124). The Map Explorer tablists attached source drawing (page 126)s, databases, queries, and link templates.The Display Manager (page 122) tab controls display layers and their style (page126)s. The Map Book tab displays the map books available for publishing, andlets you create new map books. You can resize the Task Pane and place it whereyou want.

theme A style (page 126) that varies the appearance of an element in a layerbased on the value of a specific property (page 124). For example, instead ofcoloring lakes blue, you could vary the shade of blue based on the depth of

the lake. Instead of choosing one line width for all roads, you could vary theline width based on number of lanes.

vector A mathematical calculation of an object with precise direction andlength. Vector data is stored as X,Y coordinates that form points, lines, andareas. Compare with raster (page 125).

viewport (paper space) A view of modelspace from a layout.

workspace Contains the commands and tools for specific tasks. The Map 3DFor Geospatial workspace is tailored for working with spatial feature (page 123)swhile Map 3D For Drawings is optimized for working with drawing objects.

To change your workspace, click View menu ➤ Menu/Toolbar Layout. Clicka workspace.

zoom To change the display magnification so that it focuses on progressivelysmaller areas (when you zoom in) or larger areas (when you zoom out) of animage.

zoom extents To magnify a drawing based on its extents so that the viewshows the largest possible view of all spatial objects.
