Hi Ypnos,

See here: http://moi3d.com/forum/index.php?webtag=MOI&msg=759.12 for an explanation.

Basically the way that MoI objects are structured does not lend solids in general to being squished around with point cages.

MoI is not really focused on point cage modeling techniques (except for points on curves) - instead MoI is focused on techniques involving drawing curves and then constructing surfaces from those curves by lofting, sweeping, revolving, etc..

In a certain sense it is more like illustration where you more directly draw the outline of your shape and then fill in the surfaces. Usually you will build your model in different pieces using these techniques, then use booleans to combine the pieces together, and then possibly use fillets to smooth out the sharp edges from the booleans.
