Shelling complex surfaces
Shelling complex surfaces
(OP)
I'm battling what I think should be a fairly simple problem but am drawing a blank. I have an imported solid of a model that has some fairly complex surfaces. I'd say a doll head is a pretty good example of what I'm dealing with. What I need to do is shell it out. I've tried shelling the solid but get a minimum radius of curvature error. So I thought I'd surface it and thicken the surface but that didn't work either. Am I going about this the right way? Any suggections? Thanks - DadeLar

You will have to live with a thinner wall thickness or increase the outer radius.

So it can take some trial-and-error, but will almost always work if done this way.
After all surfaces are represented in the offset chunks, you can trim/knit them to create the inner surface. Use that surface to perform a surface cut to eliminate the internal solid mass, and you're left with your shell.

It seemed to have more luck dealing with the resulting geometry than the shell command which I've found to be less than robust.

For a manual method, you may want to select all faces on the outer surface of this 'doll head'. Select offset surface and enter a value of 0. This will copy the surface, and this shoulb be considered a singualr knitted surface if it was a solid. Then offset the surface twice, once inward and once outward. What is the max you can offset it inward without collapsing it about a min rad of curvatue ? What is the max you can offset it outward while maintianing the form? You could then insert a plane down at the 'neck' and trim these inward and outward surfaces to it. Create a planar surface between these inward and outward surfaces. You now should be able to knit all three together with try to form solid checked. If this is not possible, then you are going to have to use more complex techniques like the ones mentioned by jeff and CBL.

If you shell out of course the radii will be larger versus the interior model you started with, is this a problem?
Can you use offset surfaces command ?
