AutoCAD 3D Modeling: Predefined Meshes

August 8, 2003

Sometimes you might need to create some 3D geometrical shapes such as spheres, cubes, pyramids, and so on. There is a command called 3D that helps you to create such models. If you invoke 3D from Draw menu a special type of dialog box called image tiled menu will appear [Figure 1]. You may double-click the slide or the text to the left to invoke the option you are looking for.

  • This tutorial is designed for AutoCAD 2004 though might be applicable for other releases.
  • In this tutorial user entries are in boldface.
  • The  8  symbol represents pressing Enter.
  • To learn more on image tile menus as the one shown above in Fig. 1, read, AutoCAD menus: Image Tile Menus

1. Download r16_pred_meshes.dwg

Note: If you are using AutoCAD 2002 or an earlier release download r15_pred_meshes.dwg

2. Open the drawing in AutoCAD.

3. Enable SE Isometric view point:

Command: -view 8

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

Note: For more information on viewing 3D models read the following tutorial: AutoCAD 3D Modeling: 3D Views

4. Invoke Zoom-All.

5. On Draw menu click Surfaces > 3D Surfaces.

6. On 3D Objects dialog box double click the sphere slide.

7. Draw a sphere based on the following inputs [Figure 2]:

Specify center point of sphere: -2,0,0 8

Specify radius of sphere or [Diameter]: 3 8

Enter number of longitudinal segments for surface of sphere <16>: 36 8

Enter number of latitudinal segments for surface of sphere <16>: 36 8

8. Repeat the command again. Draw a cube with the following settings [Figure 3]:

Specify corner point of box: 4,4,-2 8

Specify length of box: 4 8

Specify width of box or [Cube]: c 8

Specify rotation angle of box about the Z axis or [Reference]: -10 8

9. With the same method draw a cone [Figure 4]:

Specify center point for base of cone: 5,-3,-1 8

Specify radius for base of cone or [Diameter]: 4.5 8

Specify radius for top of cone or [Diameter] <0>: 1.5 8

Specify height of cone: 5 8

Enter number of segments for surface of cone <16>: 36 8

10. Draw other models such as pyramids, domes, and dishes with this method [Figure 5].
