In the first chapter we analyzed the application of AutoCAD editing commands commonly used in 2D, such as
ERASE, which work exactly the same way in 3D as in 2D. Others, such as
OFFSET depend on the object plane. Some more, such as
ROTATE depend on the current user coordinate system.
In this chapter we present some commands that are specific to 3D operations that can be applied to any object. The editing commands specific to solids and surfaces are the subject of the next chapter.
The topics covered in this chapter are:
How to rotate objects around an axis
How to get mirrored objects
How to align objects
How to apply multiple, equally spaced copies
How to modify objects with grips
How to modify fun faces, edges, and vertices
