selected 3D solids.
System Variables

Sets the color for interference objects.
INTERFEREOBJVS
Sets the visual style for interference objects.
INTERFEREVPVS
Specifies the visual style for the viewport during interference checking.
Create Surfaces
Create procedural surfaces and NURBS surfaces from curves or by combining
or extending existing surfaces.
Overview of Creating Surfaces
Surface modeling provides the ability to edit multiple surfaces as an associative
group or in a more free-form way.
In addition to 3D solid and mesh objects, AutoCAD offer two type of surfaces:
procedural and NURBS.
Procedural Surfaces can be associative, maintaining relationships with
other objects so that they can be manipulated as a group.
NURBS Surfaces - are not associative. Instead, they have control vertices
that allow you to sculpt shapes in a more natural way.
Use procedural surfaces to take advantage of associative modeling, and use
NURBS surfaces to take advantage of sculpting with control vertices. The
illustration below shows a procedural surface on the left, and a NURBS surface
on the right.
