[C# CONNECT update7] Parametric Solids


I'd need some explanations about the new element type "Parametric Solid" (i.e that kind of solid created by extrusion).

I noticed that the MsdElementType is set to106 (unnamed, since this number is not mapped in the MsdElementType enum (?) ).

So it's not a Solid or a SmartSolid or else, it's a new type of its own. What is it?

How can we operate on this new solid type, like programmatically edit the value of a feature bound to it, or even add a new feature? 

Am I missing something in the documentation?
