Create Solids and Surfaces from Objects

Concept

Procedure

Quick Reference

You can create surfaces from existing objects in your drawing.

With the CONVTOSURFACE command, you can convert any of the following objects into surfaces:

• 2D solids
• Regions
• Bodies
• Open, zero-width polylines with thickness
• Lines with thickness
• Arcs with thickness
• Planar 3D faces

You can create surfaces from 3D solids with curved faces, such as a cylinder, with the EXPLODE command.

You can use the PLANESURF command to create a planar surface. Use either of the following methods:

• Select one or more objects that form one or more enclosed areas
• Specify the opposite corners of a rectangle

When you specify the corners of the surface, the surface is created parallel to the workplane.

You can use the CONVTOSOLID command to convert the following objects into extruded 3D solids:

• Uniform-width wide polylines with thickness
• Closed, zero-width polylines with thickness
• Circles with thickness

The DELOBJ system variable controls whether the objects you select are automatically deleted when the surface is created or whether you are prompted to delete the objects.
