  Not being a programmer I can only suggest that it might be useful in
csg operations - if the program had the ability to internally tessellate
primitives. And yes I do see that this would be a definite plus for
the program. The ability to export to other 3d formats would be a side
benefit from this and not the major reason for implementing it.
