Complex Surface Model Editing
Complex Surface Model Editing
(OP)
Hi there
I'm looking for some help with a complex imported IGES model. It is basically a model of a bone in the finger of a human hand. It was imported as part of an assembly of a complete hand and each bone is separated into parts within the assembly.
Basically I want to 'shell' the bone leaving it hollow on the inside with a hole at each end of the bone to allow access into the hollowed area. Because it was imported as IGES it has approximately 300+ surfaces and I'm having difficulty in creating this shell effect. I've also tried to offset a surface from the original at 0mm and then subtract the imported surface away but there is a relationship between the two so this doesnt seem possible either.
Does anybody have any ideas with this one?

If you bring it in as a surface model only, you might also get away with a surface thickening operation, but it also might fail depending again on surface complexity, radii, etc., as it would be thickened inwards.
Have you tried knitting surfaces, etc. to reduce the surface count?

RE: Complex Surface Model Editing
Shell no longer requires an open face--check it out. Very useful feature sometimes. This allows the holes to be punched out after shelling.
However, depending on the original surfaces imported, shelling at a desired thickness may be a big problem. Often, thin shells are possible, while thicker shells omit faces and cause other computational problems. If this is the case, perhaps a simplification of the process can be done, such as making revolved cuts where the holes are needed where the holes open up inside the bone, but don't necessarily follow the outer surfaces precisely. Hard to tell what is ultimately required.
You may also be able to knit, offset, and cut with selected surfaces to obtain a mostly-shelled part.
