Chapter 7. Editing Solids and Surfaces
An important part of any 3D project is combining solids and editing solids and sur-
faces. Among other useful commands, we can union, subtract, intersect, and cut 3D
objects, as well as applying fillets and chamfers to objects edges. In this chapter, we
present all the main commands for editing solids and surfaces.
The topics covered in this chapter are as follows:
• Applying unions, subtractions, and intersections
• Cutting and dividing 3D objects
• Filleting and chamfering edges
• Editing faces, edges, and volumes of solids
• Creating copies and offsets from edges
• Projecting objects onto 3D objects
• Adding thickness to surfaces
Composite objects
Until now, we dealt with the creation of 3D objects. Now, let's see how to combine and
modify them.
Unions, subtractions, and intersections
Three basic operations to combine objects are unions, subtractions, and intersec-
tions. These are called Boolean operations and can be applied to solids, surfaces,
and regions.
The commands to perform unions, subtractions, and intersections can be found on
the ribbon, Home | Solid Editing panel, on the Modeling toolbar, and on the Menu
bar, Modify | Solid Editing :
