- Optionally rotate the 3D view. The camera direction in the 3D view determines the projection vector. For example, a top view will project onto the XY plane. The projection vector is ignored for projections created from Arch SectionPlanes.
- Optionally select one or more objects.
- There are several ways to invoke the command:
- Press the Shape 2D view button.
- Select the Modification → Shape 2D view option from the menu.
- If you have not yet selected an object: select an object in the 3D view.
- The projected objects are created on the XY plane.
