This object is automatically inserted if the model includes symmetry planes defined in DesignModeler (using the Symmetry or Enclosure feature).
Manually insert the object using any of the following methods after you highlight the Symmetry object:
- Select Symmetry Region (or Linear Periodic) on the Symmetry Context Tab.
- Right-click the Symmetry object, on an existing Symmetry Region, Periodic Region, or Cyclic Region object, or in the Geometry window Insert > Symmetry Region (or Linear Periodic).
Linear Periodic: The Symmetry Context Tab (as well as the context menus) contains a Linear Periodic option. When selected, a Symmetry Region object is placed in the Outline with the Type property automatically set to Linear Periodic.

In addition to common right-click options, relevant right-click options for this object include:
