Default Menu : Draw | 3D Object | 3D Profile Based | Simple Extrude

Palette : 3D Model | 3D Object | Simple Extrude

A 2D profile can be extruded to create an equidistant extrusion about the profile.A closed profile will produce a solid object.

Right click in the editor and turn the view to Isometric South East. The profile should be similar to the illustration, below. 

Notice how the Workplane is aligned to the south east view, shown by the arrow, below.

The extrusion direction can be observed from the sketch below.  Therefore, to create a below Workplane extrusion, a negative value will be used.

Select the Simple Extrude tool from the menu options above, then select the profile.

Drag the profile in a negative direction, then use TAB to access the Height field. Input -100 and press enter.

The result should be similar to the illustration, below.
