AutoCAD 3D Modeling: Revolved Solids

August 21, 2003

The REVOLVE command creates 3D solids by revolving closed polylines, circles, ellipses, closed splines, or regions about an axis in 3D space. The following tutorial shows you how.

Notes:

  • 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_revolved.dwg.

Note: If you are using AutoCAD 2002 or an earlier release download r15_revolved.dwg.

2. Open the drawing in AutoCAD. The drawing consists of a closed polyline [Figure 1].

3. Invoke REVOLVE (Draw menu > Solids > Revolve).

4. Select the lower left corner of the polyline as the first axis point:

Specify start point for axis of revolution or
define axis by [Object/X (axis)/Y (axis)]:

5. Select the other endpoint of the vertical line as the second point for axis of revolution:

Specify endpoint of axis:

6. Enter 360 degrees as the angle of revolution:

Specify angle of revolution <360>: 360 8

7. Alter the view to SE Isometric [Figure 2].

Command: -v
-VIEW Enter an option [?/Orthographic/Delete/Restore/Save/Ucs/Window]: seiso 8

8. Alter the shade mode to Gouraud shaded [Figure 3].

Command: shademode 8
Current mode: 2D wireframe
Enter option [2D wireframe/3D
wireframe/Hidden/Flat/Gouraud/fLat+edges/gOuraud+edges] <2D wireframe>: g 8
