AutoCAD Tutorial

AutoCAD 3D Modeling: Editing Solids, Part 9

September 19, 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; Editing Solids, Part 6; Editing Solids, Part 7; Editing Solids, Part 8.)

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

Note:  This tutorial is designed for AutoCAD 2004 though might be applicable to other releases.

1. Download and then open r16_separate_body.dwg [Figure 2].

Note: If you are using AutoCAD 2002 or an earlier release download r15_separate_body.dwg.

5. If you click any of the parts the other part is also selected. Although the parts are separate they belong to the same solid model. To separate the parts invoke Separate (Modify menu > Solids Editing > Separate).

6. Select the solid object. The model is divided into two objects now.

7. Invoke Check (Modify menu > Solids Editing > Check). Click one of the models. It is a valid ShadeManager solid.
