Create Surfaces or Solids With the Same Commands
When you extrude, sweep, loft, and revolve curves, you can create both solids
and surfaces. Open curves always create surfaces, but closed curves can create
either solids or surfaces depending on the situation.
If you select a closed
curve and click EXTRUDE, SWEEP, LOFT, and REVOLVE
on the ribbon, you create:
A solid
if the Mode option is set to Solid.
A surface if the Mode option is set to Surface.
A procedural surface if the SURFACEMODELINGMODE system
variable is set to 0.
A NURBS sur
face if the SURFACEMODELINGMODE system variable
is set to 1.
An associative sur
face if the SURFACEASSOCIATIVITY system variable
is on.
In this illustration, the same profile creates a solid (left), a procedural surface
(middle), and a NURBS surface (right).
