How do you make a polyline into a 3D face?

If your polyline border contains arc segments, you may want to refine the resulting mesh with the MESHREFINE command. This will increase the density of the small patches and more precisely fill in the arcs. The mesh can be easily converted to 3d face entities (3DFACE) just by exploding – the EXPLODE command.
