Solid edge (parasolid) has many useful features for working over 3d scans and reverse engineering.
It's mostly about segmenting a 3d mesh into simpler shapes (planes, cylinders, spheres, cones) and extracting surfaces from those segments. More complicated surfaces than planes can be extracted from a 3d scan. There is always a possibility of removing features from a 3d mesh. There is also a unique feature to boolean (subtraction) a CAD tube from a mesh and put a CAD fillet over that edge (between CAD and mesh).
I'm writing about it because it's Parasolid, so maybe it`s possible to move all those reverse engineering features from Parasolid straight to Plasticity.
and here:
To be honest, I bought Solid Edge, which is expensive mostly for those Reverse Engineering features, which are brilliant, I think.
Cheers!!!
