#### 2.1.4.2. Virtual Geometries

Virtual Geometries group together subshapes of CAD geometry parts. The subshapes are referenced by linking to features of CAD geometry parts. There are three ways to define virtual geometries:

- Directly from CAD parts through the CAD part context menu.

  Figure : Create Virtual Geometry Directly from CAD Geometry Part

- By selecting multiple CAD parts from the tree when the Virtual Geometry Properties dialog is open.

  Figure : Create Virtual Geometry Through CAD Geometry Parts in Tree

- Through face selection in the scene.

Note: Virtual geometries can only reference parts from one CAD geometry.
