Yes, I see what you are saying Michael, it says that there is a switch between solid and Smesh in the object properties, but do not know if it can change back to a solid after it is converted to an SMesh.

I downloaded the free version of Hexagon offered at Daz3d, and to my surprise, it has some very handy features. I am more used to solid modelling, so my surface modelling and it's variants need some intensive study.

I like where you are going with MOI, an excellent creation that really grabs the imagination.
