I’ve been working with Rhino’s ShrinkWrap command recently. While I’ve read many existing posts here about it, my current need might be a little different from the usual cases.
Images 3 & 4: These are some experimental attempts I made with different settings.
What I’m aiming for is a very simplified shrinkwrap result — a smooth, clean outer shell that wraps over the original geometry. I don’t need detailed surface reproduction; instead, I prefer simplicity, mainly for Boolean operations or mesh reduction workflows.
Does anyone have suggestions for settings, techniques, or maybe scripts/plugins that could help generate this kind of simplified result more efficiently?
Hi, Laurent Delrieu, thank you so much, maybe I didn’t make it clear enough, I actually need a subd grid with an error of 0.5mm.
Also, I don’t know why it runs so slowly, it takes me 3 minutes to run each time.
Hi, thanks again for the feedback — and you’re absolutely right to point out the contradiction. I didn’t express myself clearly earlier, and I appreciate the chance to clarify.
My original idea was to create a simplified mesh shell, then convert it to SubD for manual control point editing. But now I realize that might not be practical for this case.
Let me explain better what I’m trying to achieve:
I want to generate a mesh that wraps around the outer shape of the model, while ignoring deep undercuts or concave regions, such as the spaces between teeth.
The final result I’m aiming for would be similar to a horseshoe-shaped shell, cleanly covering the outer surface but not sinking into every gap.
It doesn’t need to be super low-poly or SubD-ready — the key is to have a watertight, simplified wrap that respects the overall contour, while skipping the detailed surface depressions.
Thanks again for your insights — I really appreciate the help from this community!

Thank you very much for your support!
I tried the method you shared in the link, but unfortunately the result wasn’t ideal.
I found that the wrapped mesh always gets pulled into the interior of the model — in other words, it wraps too tightly.
To give a bit more clearance, you could adjust this method so the negative offset doesn’t bring it all the way back in - so eg. you offset by +5 then offset the result of that by -4.
