The level of smoothness upon conversion depends on the mesh type setting
(
FACETERMESHTYPE (page 1291) system variable). If the mesh type is not set
to be optimized, the converted object is not smoothed.
To convert mesh objects to 3D surfaces or solids, use CONVTOSOLID (page
223) or
CONVTOSURFACE (page 225) commands.
Objects That Can Be Converted to Mesh
