Place radial grids in Unit U05 of Area A2 by specifying the settings for the coordinate system, elevation plane, radial cylinder, and radial plane in the Grid Wizard. The specifications for the radial grids are as follows:
Specify radial_grids as the reference coordinate system for the elevation planes, radial cylinders, and radial planes that you create.

6. Keep clicking the Next button until the Radial Cylinder and Radial Plane form appear.
Skip the Grid Planes and Grid Y-Planes form. You specify settings for the grid X-plane and grid Y-X-plane when you create grid X-planes perpendicular to the x-axes and y-axes of the coordinate system.
7. In the Create Radial Cylinder form, specify the following settings and click the Add button after specifying each setting.
• Radial Cylinder 1
o Reference CS: radial_grids o Start cylinder: 163 ft 3.37 in o Copies: 0
o Name rule: Alphanumeric and Percent o Type: E-W Grid Plane
• Radial Cylinder 2
o Reference CS: radial_grids o Start cylinder: 167 ft o Copies: 0
o Name rule: Alphanumeric and Percent o Type: N-S Grid Plane

18. The Select System dialog box appears. Choose the Database option. To make CS the parent system of radial_grids, select CS and click OK in the Select System dialog box.
For more information related to placing coordinate systems and rotated and radial grids, refer to Understanding the Grids Workflow: An Overview topic of the user guide

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.
