AutoCAD Tutorial

AutoCAD 3D Modeling: Editing Solids, Part 4

September 11, 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)

In this tutorial I show you how to use Delete Faces and Rotate Faces. You can reach these options through Solids Editing toolbar [Figure 1]. Both options deal with faces of the solid model.
