Tip 2 of the CAD
Quick Extrusions with Presspull
As of AutoCAD 2007,
there's no need to draw closed shapes before extruding. The Presspull tool will
find any enclosed area (just like BHATCH) and extrude it.
Any objects can be used
as boundaries; lines, circles, splines, they all work. This makes building 3D
solid models much quicker than before.
