Creating 3D PolygonMesh Objects

The 3D command creates 3D PolygonMeshes in different shapes immediately without defining entities and boundaries that already exist in the drawing.

To create a box shaped 3D PolygonMesh:

1. Type 3D at the command prompt.
2. Specify the Box option.
3. Type coordinates or click in the graphics area to specify the first corner of the box.
4. Type values or click in the graphics area to specify the length, width, and height of the box.
5. Type a value or click in the graphics area to specify the rotation angle around the Z axis.
   
   - or -
   
   Specify the Reference option to define a reference angle and a new angle to define the rotation.

1. Type 3D.
2. Specify the Cone option.
3. Type coordinates or click in the graphics area to specify the base center point.
4. Type a value or click in the graphics area to specify the base radius.
   
   - or -
   
   Specify the Diameter option, then type a value or click in the graphics area to specify the base diameter.
5. Repeat the previous step for the top radius.
6. Type a value or click in the graphics area to specify the height.
7. Type a value for the number of segments for the surface of the cone.

5. Type a value for the longitudinal segments for the surface (density of the mesh).
6. Type a value for the latitudinal segments for the surface (density of the mesh).

To create a dome shaped 3D PolygonMesh:

1. Type 3D.
2. Specify the Dome option.
3. Type coordinates or click in the graphics area to specify the center point.
4. Type a value or click in the graphics area to specify the radius.
   
   - or -
   
   Specify the Diameter option, then type a value or click in the graphics area to specify the diameter.
5. Type a value for the longitudinal segments for the surface (density of the mesh).
6. Type a value for the latitudinal segments for the surface (density of the mesh).

To create a 3D PolygonMesh:

1. Type 3D.
2. Specify the Mesh option.
3. Type coordinates or click in the graphics area for the four corner points of the mesh. If you specify points in a counterclockwise or clockwise order you get a rectangular mesh. Otherwise you get a self-intersecting PolygonMesh.
4. Type a value for the mesh size in the M direction.
5. Repeat the previous step for the N direction.

To create a pyramidal 3D PolygonMesh:

1. Type 3D.
2. Specify the Pyramid option.
3. Type values or click in the graphics area for the four corner points of the base.
4. Type a value or click in the graphics area to specify the apex point.
   
   - or -
   
   Specify the Ridge option to define two points to form a ridge instead of one point for an ordinary pyramid.
   
   Type a value or click in the graphics area to specify the first and second ridge end points.
   
   - or -
   
   Specify the Top option to create a top plane that is not parallel to the pyramid's base.
   
   Type a value or click in the graphics area to specify the four corner points for the top of the pyramid.

To create a tetrahedron (3-sided pyramid) shaped 3D PolygonMesh:

1. Type 3D.
2. Specify the Pyramid option.
3. Type values or click in the graphics area for the three corner points of the base.
4. Specify the Tetrahedron option.
5. Type a value or click in the graphics area to specify the apex point.
   
   - or -
   
   Specify the Top option to create a top plane that is not parallel to the tetrahedron's base.
   
   Type a value or click in the graphics area to specify the three corner points for the top of the tetrahedron.

To create a spherical 3D PolygonMesh:

1. Type 3D.
2. Specify the Sphere option.
3. Type coordinates or click in the graphics area for the center point.
4. Type a value or click in the graphics area to specify the radius. 
   
   - or -
   
   Specify the Diameter option, then type a value or click in the graphics area to specify the diameter.
5. Type a value for the longitudinal segments for the surface (density of the mesh).
6. Type a value for the latitudinal segments for the surface (density of the mesh).

To create a torus shaped (donut) 3D PolygonMesh:

1. Type 3D.
2. Specify the Torus option.
3. Type coordinates or click in the graphics area for the center point.
4. Type a value or click in the graphics area to specify the radius.
   
   - or -
   
   Specify the Diameter option, then type a value or click in the graphics area to specify the diameter.
5. Repeat the previous step for the tube radius.
6. Type a value for the number of segments around the tube circumference (density of the mesh).
7. Type a value for the number of segments around the torus circumference (density of the mesh).

To create a wedge shaped 3D PolygonMesh:
