AutoCAD 3D Modeling: Editing Solids, Part 1

September 5, 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.

In this tutorial I show you how to use Extrude Faces. You can reach this option through Solids Editing toolbar [Figure 1]. This option deals with faces of the solid model.

Figure 1


  • 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 r16_extrude_face.dwg. The file consists of a solid box [Figure 2].

Note: If you are using AutoCAD 2002 or an earlier release download r15_extrude_face.dwg.

2. Invoke Extrude Faces (Modify menu > Solids Editing > Extrude Faces).

3. Click inside the top face. Make sure not to click on any of the edges.

4. Press Enter. Specify the extrude height to be 1 and the taper angle 15 degrees [Figure 3]:

Specify height of extrusion or [Path]: 18
Specify angle of taper for extrusion <0>: 158

Figure 3

5. Invoke the option again. Extrude the top face with the height equal to 2 and the taper angle equal to 30 degrees [Figure 4].

Figure 4

6. Extrude the top face 10 units in negative direction. The taper angle is zero. A hole will be created in the middle of the model [Figure 5]:

Specify height of extrusion or [Path]: -108
Specify angle of taper for extrusion <0>:8
