By the end of this session, you will be able to:
• Edit the grids in a model.
A grid system is a coordinate system and a set of reference planes and/or cylinders defined relative 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 radial planes passing through the center of the cylinders.
When you select one or multiple consecutive planes (or cylinders) on the same coordinate system axis, you can edit the position of the planes using the commands displayed on the Edit ribbon.
Steps for Placing an Elevation Plane:
Placean elevation plane in a coordinate system. The settings for the coordinate system, type of elevation 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.

1. Define your workspace to show Unit U04.
2. Switch to the Grids tasks, if not already in the Grids task.
3. Set the Active Permission Group to Layout.
4. On the vertical toolbar, click the Place Elevation Plane button.

5. On the Elevation Plane Horizontal ribbon, select U04 CS as the coordinate system in the CS drop-down list, as shown in Figure 3.
Figure 3: Selection of the Coordinate System
The Type drop-down list on the Elevation Plane Horizontal ribbon displays a list of elevation plane types, which are defined in the Catalog and can be customized by the system administrator. The type of elevation plane can be used to help in the generation of 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.

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 Plane Placement command, the software prompts you to enter a point to position the plane. The Offset box dynamically indicates the distance from the reference defined by your current cursor position. You can click in the graphic view to create the plane at 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 the values. 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 the next plane position.
• The command defaults to the last used nesting level. You must set the nesting level before 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 default catalog. Nesting level can be Primary, Secondary, or Tertiary. This represents a hierarchy along an axis. Between two adjacent planes, a difference of only one level is allowed. Therefore, you can place secondary planes between two primary planes and tertiary planes between two secondary planes.
• The Copies option allows you to place multiple elevation planes. It indicates the number of additional elevation planes to be placed in the grid. By default, the value in this box is 0. With this value, a single elevation plane is placed by using the specified reference plane as the starting point and the offset as the distance to the new elevation plane.
8. On the Place Elevation Plane ribbon, set the Reference, Offset, Copies, and Nesting Level parameters, as shown in Figure 6.

9. Key in the Offset value and press the Enter key to commit the value to the database. The elevation plane will be placed, as shown in Figure 7.

10. 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.
