Creating extruded solids or surfaces

You can create three-dimensional solids or surfaces by extruding closed entities, such as polylines, polygons, circles, ellipses, closed splines, donuts, and regions. You can extrude the entity along a selected path, or you can specify its height and taper angle.

To create an extruded solid or surface  

   1   Do one of the following to choose Extrude () ():

    On the ribbon, choose Draw 3D > Extrude (in Draw 3D Solids or in Surfaces).

    On the menu, choose Draw > 3D Solids > Extrude or Draw > Surfaces > Extrude.

    On the Draw 3D Solids or the Draw 3D Surfaces toolbar, click the Extrude tool.

    Type extrude and then press Enter.

   2   Select the entity to extrude.

If you want to create an extruded surface instead of a solid, choose Mode. If an open profile is selected, a surface is created even if Mode is set to Solid.

   3   Select the extrusion path, or specify the height.
