  • In this tutorial user entries are in boldface.
  • The 8 symbol represents pressing Enter.
  • For information on creating boxes, spheres, and cylinders read, AutoCAD 3D Modeling: 3D Primitive Models, Part 1

1. Download r16_primitives.dwg.

Note: If you are using AutoCAD 2002 or an earlier release download r15_primitives.dwg.

2. Open the drawing in AutoCAD.

3. Invoke CONE (Draw menu > Solids > Cone).

4. Draw a cone [Figure 2]:

Command: cone8
Current wire frame density: ISOLINES=4
Specify center point for base of cone or [Elliptical] <0,0,0>:
5,58
Specify radius for base of cone or [Diameter]:
1.28
Specify height of cone or [Apex]:
38

5. Create a wedge (Draw menu > Solids > Wedge) [Figure 3]:

Command: wedge8
Specify first corner of wedge or [CEnter] <0,0,0>:
Specify corner or [Cube/Length]:
2,28
Specify height:
38

6. Create a tube by using TORUS (Draw menu > Solids > Torus):

Command: torus8
Current wire frame density: ISOLINES=4
Specify center of torus <0,0,0>:
5,18
Specify radius of torus or [Diameter]:
2.28
Specify radius of tube or [Diameter]:
0.48

7. Alter the shade mode to Gouraud shaded [Figure 4].
