Choose a Representation for the rack. The choices are Top, Wire 3D, and Solid.
NOTE: For side representations: After you pick the location for the top of the rack, you will be prompted to cursor select an axis orientation for the rack. If you select Angle (from the Conversation Bar) at this point, a dialog box will appear which allows you to enter the angle into a text field.
