operations to create solids whose shapes conform to a path you specify. Then modify or recombine

objects to create new solid shapes.
Complex solid shapes are easier to construct and edit than legacy wireframe models. However, if

needed, you can explode a solid to break it down to regions, bodies, surfaces, and wireframe objects.

4.10.1 EXTRUDE

Creates unique solid primitives by extruding existing two-dimensional objects. EXTRUDE also
creates solids by extruding two- dimensional profiles along a specified path. You can extrude

multiple objects with EXTRUDE.

To extrude an object

1. Click Draw Modeling Extrude
2. Select the objects to extrude.

3. Specify the height.
Command entry: EXT

4.10.2 REVOLVE

Creates a Solid by revolving a two-dimensional object about an axis. You can revolve closed objects
to create 3D solids and open objects to create surfaces. Objects can be revolved 360 degrees or

another specified angle.

To revolve objects about an axis
1. Click Draw Modeling Revolve

2. Select the objects to revolve.
