AutoCAD 3D Modeling: Editing Solids, Part 6

September 15, 2003

The SOLIDEDIT command offers different options to edit solid objects. The options cover face editing, edge editing and body editing. I have designed a series of tutorials to cover all these options. Every tutorial explains one or more options. (See also: Editing Solids, Part 1Editing Solids, Part 2Editing Solids, Part 3; Editing Solids, Part 4; Editing Solids, Part 5)

In this tutorial I show you how to use Copy Faces and Color Faces. You can reach these options through Solids Editing toolbar [Figure 1]. The options deal with faces of solid models.
