True 3D solid objects have properties, volume, and mass, that are not shared
by objects created with thickness or closed surfaces. You can check whether
an object is a valid 3D solid by verifying whether it is listed as 3D Solid on
the Properties Inspector. You can also use SOLIDEDIT to verify whether a solid
object is a valid 3D solid object.
Pressing or Pulling Areas and Faces
Get visual feedback as you extrude objects and offset 3D solid faces.
The program responds differently, depending on the type of object you select
to press or pull.
Press and Pull to Create Holes and Solid Extrusions
Press in or pull out bounded, or closed, areas or objects to create holes and
3D solid extrusions. You can select within a closed object, an area, or a face
that is imprinted on a solid object.
In combination with imprinted faces, you can form complex shapes using
press or pull operations to create extrusions and notches. The following object
was formed using press and pull operations on an imprinted pyramid.
