We will assign the new layers to the specific tools as we model; and create more if needed during the modeling process. Layer naming as per “Building 2000 classification” can be found in “RT 1510919” card. You can use the library services to download the RT card. We will also check layers and importing the Finnish layers in other lab sessions. Modeling the building elements: Discipline specific guidelines for modeling requirements can be accessed from “Common BIM Requirement – COBIM 2012” documents.

We will start modeling the outer wall. Refer to the pdf drawing attached for the details about the width, length and other details of walls. Create a composite wall “OW 01” with the details as shown: Access the Composite wall from Options à Element attributes à Composites.. Create “new” or “duplicate” and modify the following details
Brick – 75mm; type : finish Insulation – 90mm; type : other Reinforced Concrete -‐ Structural; type: core
Plaster – gypsum – 15mm; type: finish
Note: Brick element in this composite wall is exposed to outside and Gypsum plaster is
the exposed to interior spaces.

“Double click” 1.Floor to make it active. Select “wall” tool from the design tools. Click the “settings dialog” icon to go to the properties (shortcut Ctrl + T / Cmd+T) and make the following modifications. Wall top: 2.Floor (Home+1) Home story: 1.Floor (Current) Wall type: Composite – OW 01 Reference line: Outside face Structual function: Load-‐bearing element Position: Exterior Element classification: Archicad type Note: Elements modeled can be individually classified as wall; column or other
elements; however “archicad type” refers to selected tool while creating the element “In this case: wall”
Layer: 01_OW_OuterWall.AR After the modifications; click Ok and then select “Chained geometry method” from the “Info box”. Press the “black arrow” for a longer period to access the options and select the Chained method.
Move the cursor to the origin “x” of the drawing area in archicad and click once the cursor changes to a small tick mark or a blue circle indicating the “x” appears. Move the cursor to the right and enter “6000” in the distance field and “0” in the angle field if it is different. (Press “tab” button in the keyboard or the first letter of the fields to move from one to another). Once finished, press enter and then move the cursor vertically up.
Complete the outer wall by entering relevant dimensions.

Check “generic perspective” in navigator project map under 3D. Various elevation views are automatically generated that are linked with the “elevation markers” in the drawing area. All of the outer walls are automatically grouped. In case of need to modify the individual walls, they first need to be “ungrouped” or “suspend group”. Edit à grouping à suspend group (check the similar icon on the quick access toolbar) Press “esc” couple of times to make the arrow selection tool active. Openings in 1.Floor -‐ Window Double click the “window” tool to access window settings. Select “Double sash window 19” and modify the following settings: Width: 2000 mm Height: 1350 mm Sill level: 750 mm
Structural function: non-‐load bearing Position: exterior
Open the “basic window settings and make the following modifications:

Go to “wall opening”; select Closure type: Prefabricated cavity closure. The reveal dimensions should automatically change to “90” if not change “reveal to – no reveal”. If it still does not change then do it manually. Click on the icon next to “Prefabricated cavity closure” and check mark -‐ Turn plaster automatically for inside face if it is not automatically on.
If you want to turn the external brick face, you need to modify the “thickness limit” more than the brick skin thickness and put the check mark on for outside face.
Put “outside casing” and “metal sheet” sill with the following settings:
All of the model element materials can be changed through “model attributes” in the basic window settings
Click ok and move the cursor to the center of the external face of the bottom most wall (southern wall). The wall is highlighted as blue and the cursor changes to “Mercedes” symbol with a small “plus” mark generated at the center of the wall. If the mid point is not found, check the snap settings

Move the cursor near the mid-‐point (external face of the wall: the sun symbol in the window defines outside) and then click once the cursor changes to a “tick mark”. After the first click, move the cursor to outside or inside areas and click to define the opening orientation of the windows (in this case, outside to left is defined)
Quick options and other tool palettes can be accessed from Window à palettes Complete all the windows as shown:

Make composite slab with following details:
Options à Element attributes à Composites.. “Slab 225 RCC with parquet_1.floor” for 1.floor slab (Thickness total: 350mm). Remember to update the “element type”.
“Slab 150RCC with parquet” for 2&3. Floor Slab (Thickness total: 255mm). Remember to update the “element type”.
Select “slab” tool and modify the following settings as in right picture:
Sunil Suwal 9
Click ok and change the “geometry method” to “polygonal” to pick up the external corners (individually) of the core element of composite wall.
Select this option if you want to do it differently.
After pressing “Ok” from the slab settings dialog box; move the cursor to the internal enclosed area. Press “spacebar (a magic wand appears)” and click anywhere inside or on the top of the wall to create a slab automatically. Remember that you have to keep on pressing the “spacebar” and leave it only after clicking. The slab might not be visible in 2D floor plan, however it will be there if you have done the process correctly. Move the cursor to the internal room area and press “shift” from the keyboard. The slab will be highlighted with blue color and “click” to select it.
Modify the boundary of the slab to place it in the correct position (red circled corners of the core element of the composite wall)
“Click” either on the black hotspot or the boundary of the slab to bring in the “pet palette”. Select “offset all edges” and offset to the right place; that is the external boundary of the core element of the wall.
We will make two sections along X-‐X and Y-‐Y direction. It is always good to press “esc” couple of times to end the previous command or activate the “arrow” selection tool.

Select “section” tool from the document group on the left; double click or Ctrl+T to go to the section settings dialog box. Modify the settings as needed. Reference ID and name in “general”. Marker details like linetype, color; font and how it is displayed in “Marker”. “Model display” – how different cut and uncut elements are visible.
Check all the necessary details and try to make similar as in the picture below: The markers are put in the center of door and window objects
Text for the section markers can be changed by dragging from one place to another once selected; “marker text position mirrored” should be on for shifting both of the text. Check “S-‐02” to see the details as how the wall; door and slab intersect each other. Calculate the “sill to story” value and modify so that the threshold and slab are at the same level. You can also modify the surface definition of threshold similar to the slab. Foundation level: “0. Foundation” We will make the foundation level using profile wall. Open Window à palettes à profile manager. Select “custom profile” to open a blank profile. Make a “foundation” profile wall with the details as shown in the picture using “fill” tool. Select “concrete block structural” as the fill material.

Note: Remember the “x” origin to be placed as in the picture. “x” origin references the starting point of the wall as well as the location of the wall we draw. Once the profile is complete, click “store profile” in the profile manager window and save it as “Foundation”. “Use with” in the profile manager states as where this profile is to be used; activate wall in this section if it is not on by default After the profile is stored; activate 0. Foundation by double clicking it the stories in navigator project map. Turn on the trace. View à trace Then choose 1. Floor as the reference for trace. View à trace options à Above current story to make the 1. Floor visible in 0. Foundation floor. Select “wall” tool and “chained” method of drawing. Double click the “wall” tool or press “Ctrl+T” to go to the settings dialog window. Choose the “ complex profile” type and saved “foundation” profile. Assign the layer to “01_FW_Foundationwall.AR” and check the settings. In the drawing window; click on the internal points of the “outer wall” to place the foundation. After the first point, rough top view of the foundation is visible; align the foundation wall as per the outer wall.
