As you convert objects to surfaces, you can specify whether the resulting object
is smooth or faceted.

When you convert a mesh, the smoothness and number of faces of the resulting surface
are controlled by the SMOOTHMESHCONVERT system variable. Whereas the previous example
shows a conversion to a smooth, optimized surface, the following example shows a conversion
to a faceted surface in which the faces are not merged, or optimized.

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

Objects That Can Be Converted to 3D Surfaces

You can select the objects to convert before you start the command.

The DELOBJ system variable controls whether the geometry used to create 3D objects
is automatically deleted when the new object is created or whether you are prompted
to delete the objects.

The following prompts are displayed.

Select objects

Specifies one or more objects to convert to surfaces.

If one or more objects in the selection set are invalid for the command, you will
be prompted again to select objects.
