You can remove redundant edges or vertices that share the same surface or
vertex definition. This operation merges adjacent faces and deletes all
redundant edges, including imprinted and unused edges.
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 palette. You can also use SOLIDEDIT to verify whether a solid
object is a valid 3D solid object.
To remove redundant lines from a 3D solid object
1 Click Home tab ➤ Solid Editing panel ➤ Solid Editing flyout ➤ Clean.
2 Select the 3D solid object.
3 Press Enter to complete the command.
To validate a 3D solid object
1 Click Home tab ➤ Solid Editing panel ➤ Solid Editing flyout ➤ Check.
2 Select the 3D solid object.
3 Press Enter to complete the command.
If the object is a valid 3D object, a message is displayed at the Command
prompt. If it is not valid, you continue to be prompted to select a 3D
solid.
