Smooth, optimized.
The resulting model is smoothed, with merged faces (SMOOTHMESHCONVERT = 0).
Find
Smooth, not optimized.
The resulting model is smooth, with the same number of faces as the original mesh object (SMOOTHMESHCONVERT = 1).
Find
Faceted, optimized. The resulting model is angular, with merged, planar faces (SMOOTHMESHCONVERT = 2).
Find
Faceted, not optimized. The resulting model is angular, with the same number of faces as the original mesh object (SMOOTHMESHCONVERT = 3).

Troubleshooting
In some cases, an error message results when you try to convert surfaces and meshes to a 3D solid. The following suggestions may be able to resolve the issue:
Surfaces might not completely enclose a volume. If you extend the enclosing surfaces through and past the other surfaces, this can reduce the chance of a small gap.
Meshes edited using gizmos can sometimes have gaps between the faces. In some cases, you can close these gaps by first smoothing the mesh object.
If you have modified a mesh object so that one or more faces intersect faces in the same object, you cannot convert it to a 3D solid.
