AutoCAD 3D Modeling: Editing Solids, Part 7

September 16, 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.)

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

  • This tutorial is designed for AutoCAD 2004 though might be applicable to other releases.
  • In this tutorial user entries are in boldface.
  • The 8 symbol represents pressing Enter.

1. Download and then open r16_cc_edges.dwg [Figure 2].

Note: If you are using AutoCAD 2002 or an earlier release download r15_cc_edges.dwg.

2. Switch to 2D Wireframe shade mode [Figure 3].

3. The drawing is in perspective projection mode. Most of AutoCAD commands are not applicable in this mode. Let's switch to parallel projection. Invoke 3DORBIT (View menu > 3D Orbit).

4. Right-click in drawing area. Select Projection > Parallel [Figure 4].

5. Press Esc to exit the command. The projection mode is set to parallel [Figure 5].

10. Invoke Copy Edges (Modify menu > Solid Editing > Copy Edges).

11. Select the edge to the left.

12. Specify the displacement vector as 0,0,3 to move the copied spline 3 units along Z axis:

Specify a base point or displacement: 0,0,3 8
Specify a second point of displacement: 8

13. Enable Gouraud+Edges shaded mode [Figure 8].
