AutoCAD uses a 3rd-party ACIS kernel (engine) for their 3D solid primitives.
To do a true conversion you would have to purchase the kernel ($$$) from the
vendor.  The utility I wrote will work for primitives, but it's not a true
conversion utility.  It converts 3d faces and primitives, but it must be
used when creating the model.
