Session 3: Editing Grids
Objective:
By the end of this session, you will be able to:
•
Edit the grids in a model.
Prerequisite Sessions:
•
SP3D Overview
•
SP3D Common Sessions
•
Grids: An Overview
Overview:
A grid system is a coordinate system and a set of reference planes and/or cylinders definedrelative to that coordinate system. You can create, edit, or delete the reference planes/cylinders.
•
The Place Elevation Plane command creates one or more elevation planes.
• The Place Grid Plane command creates one or more planes along either the x (or East)axis or the y (or North) axis.
• The Place Radial Grid command places one or more concentric cylinders or radialplanes passing through the center of the cylinders.
When you select one or multiple consecutive planes (or cylinders) on the same coordinate systemaxis, you can edit the position of the planes using the commands displayed on the Edit ribbon.
Steps for Placing an Elevation Plane:
Place an elevation plane in a coordinate system. The settings for the coordinate system, type ofelevation plane, reference plane, and offset are as follows:
• Coordinate System: U04 CS
• Type of Elevation Plane: Top of Steel
• Reference: Origin
• Offset: 26 ft 0.00 in
• Copies: 0
•
Nesting Level: Primary
The new elevation plane created will generate grid lines as shown in Figure 1.

The Type drop-down list on the Elevation Plane Horizontal ribbon displays a list ofelevation plane types, which are defined in the Catalog and can be customized by thesystem administrator. The type of elevation plane can be used to help in the generationof Drawings and Reports.
6.
In the Type drop-down list, select the Top Of Steel option as shown in Figure 4.

7.
Click the Properties button to open the Elevation Plane Properties dialog box. Set
Naming Rule to Imperial Position, as shown in Figure 5.
Figure 5: Naming Rule Option in the Elevation Plane Properties Dialog Box
The next step is to specify values for the Reference, Offset, Copies, and Nesting Level parameters on the Elevation Plane Horizontal ribbon:
•
The Reference can be the origin or a selected elevation plane.
•
When you are in the Elevation Plane Position smartstep of the Elevation PlanePlacement command, the software prompts you to enter a point to position theplane. The Offset box dynamically indicates the distance from the reference definedby your current cursor position. You can click in the graphic view to create the planeat a graphically selected location. If you use the step function of the PinPoint command, this can be a very easy way to position the planes without keying in thevalues. If you key in an offset, the plane is placed when you press the Enter key. After the elevation plane is created, the command cycles to again accept input for thenext plane position.
•
The command defaults to the last used nesting level. You must set the nesting levelbefore entering an offset by data point or by key in since that creates the plane.
•
The nesting level is used by some of the naming rules provided in the defaultcatalog. Nesting level can be Primary, Secondary, or Tertiary. This represents ahierarchy along an axis. Between two adjacent planes, a difference of only one levelis allowed. Therefore, you can place secondary planes between two primary planesand tertiary planes between two secondary planes.
•
The Copies option allows you to place multiple elevation planes. It indicates thenumber of additional elevation planes to be placed in the grid. By default, the valuein this box is 0. With this value, a single elevation plane is placed by using thespecified reference plane as the starting point and the offset as the distance to thenew elevation plane.

Now, key in the Offset value as 15 ft and press the Enter key to commit the transaction.
The view will now resemble Figure 8.

Press the ESC key to exit the command.
Steps for Editing Single Elevation Plane:
Editing an elevation plane is very similar to creating the plane. When you select the plane byclicking it in the Workspace Explorer or on the graphic Ruler, the Edit ribbon for the elevationplane is automatically displayed. To change the offset of the elevation plane currently at 15 ft,perform the following steps:

1.
Click the Select button on the vertical toolbar, as shown in Figure 9.
Figure 9: Select Button on the Vertical Toolbar
2.
Set the Locate Filter to Grids Entities, as shown in Figure 10.
Figure 10: Grids Entities Selected in the Locate Filter Drop-Down List
Tip:•
While working in the Grids task, you can use the Grid Entities filter to locateany grid system design objects, such as coordinate systems, elevation planes,
and grid planes. Since it is easy to point to what you want graphically in the Workspace Explorer without getting the Quick Pick. It is best to set the Locate
Filter to Grids Entities and leave it.
3.
Select the elevation plane (at 15 ft) to be edited in the Workspace Explorer, as shown in
Figure 11.

Tip:• You can also select the plane by clicking the check mark on the Ruler. Display
the Rulers for a grid system by using the View > Rulers… command.
4.
Key in the new offset value, 10 ft, in the Offset box. The changes are committed to thedatabase as you enter them through the controls on the Edit ribbon. The ribbon remainsdisplayed until you select something else in the SP3D window.

Tip: • To change the position of the plane by graphic entry of a point, click the
Elevation Plane Position smartstep next to the Properties button, as shown inFigure 13.

You can edit all the properties of the elevation plane, including the permissiongroup of the plane, by clicking the Properties option on the Edit ribbon, asshown in Figure 14.

Steps for Editing the Positions of Multiple Elevation Planes:
You can edit the positions of multiple consecutive elevation planes. When you select multipleconsecutive elevation planes, the Edit ribbon for changing multiple planes is displayed. You canedit the common properties of the elevation planes such as the nesting level, type, andpermission group. You can also edit the positions of the elevation planes.

•
The Edit ribbon for modifying multiple planes displays, as shown in Figure 18.There are two position editing options provided in the Reference drop-down liston the ribbon:
o Relative: The Relative option moves the planes such that the distancebetween them is equal to the offset you enter. The first plane of the set
remains in the same position.o Previous: The Previous option moves the entire set of planes, keeping
their relative positions to one another but changing the offset from thefirst plane of the set to the previous reference plane. This option is notavailable if there is no plane at a position in front of the selected set ofplanes.
Figure 19: Edit Ribbon for Multiple Planes
4.
Type a new offset value 15 ft in the Offset box with the Relative option selected in theReference drop-down list. This will change the offset between the two elevation planes,
as shown in Figure 20.

Steps for Placing and Editing a Grid Plane:
Placing and editing a grid plane is exactly the same procedure as placing and editing anelevation plane. The axis control defines the axis on which the planes will be created. To place

Press the ESC key to exit the command.
Steps for Placing and Editing a Radial Grid Cylinders:
Placing and editing a radial grid cylinder or plane is exactly the same procedure as placing andediting an elevation plane. The Axis control selection of C creates the cylinders. The Axis controlselection of R creates the radial grid planes.
As with the rectangular grid planes, a smartstep is provided to select which elevation planes willcreate grid lines and arcs at the intersection with the radial grid cylinders and planes. Radial gridcylinders and planes together form a radial grid system, as shown in Figure 26.
In the Offset box, key in the offset between the grid planes as 5 ft and press the Enter key. The radial grid cylinder will be placed, as shown in Figure 28.
