Ok, thanks, might play around with those. Being focussed, doing one thing really well is probably one of the biggest advantages of MoI :)
Edit: Oh, SpaceClaim is a little outside of my budget I fear... But for a start Blender with the Construction Lines plugin is probably good enough for mesh stuff.
> Ok, so the face dimensions are much larger, so it doesn't only affect the local area but the entire object?
Yes that's correct that the dimensions of a face's "underlying surface" can be much larger than its current active area. You'll get that when you do things like booleans. After the boolean is done the surfaces all stay the same and they get new trimming boundaries on them.
When you pull around surface control points in a situation like that then it's pretty easy for the modified surface to no longer intersect with the other ones that it was intersected with to produce the current trim boundary.
So usually in CAD programs you do not form things by moving around surface control points as you do in a poly modeling program.
You can do it in some areas but not just anywhere.
> (Different from the example in the faq, where unaffected points of the same object were editible?).
Well it's the same as in the FAQ - the FAQ shows how editing control points on a plane where there was an edge formed by the intersection between the plane and a cylinder will open up a gap.
