Any ideas on how to relax a shape around another shape? I’m trying to shrink wrap objects with another object but I just cant get it. Maybe my approach is wrong? I’ve got 4 blocks encased in a larger block. The four smaller blocks are static and I want the larger block to shrink around them. The main problem im having is that the blocks don’t seem to react at to each other at all. [image]shrinkwrap.gh (33.6 KB)

i believe you need an initial position outside of the object which you have set as a collision not inside, that will probably arrest the object rather.

I’ve tried that… I’ve tried just about everything but the kitchen sink. Definition is a bit of a mess by now because I’ve been tinkering with it for so long. Setting for K2 can be so finicky at times and there’s not much documentation to help. Any thoughts @DanielPiker?

That’s exactly what I was trying to do! Awesome thank you! I still don’t understand why my definition didn’t work though. Was it my terrible meshes?

Hi Daniel, I tried your definition, but I didn’t have clean & combine version 1.000. So I replaced it with another version and connected it with other components. Now I’ve got a problem with the unflatten tree component. Please see attached file and I’d really appreciate it if you can help me find the problem. Thank you.

Hi Tina, There’s a more recent shrink wrap example file here: [image] Shrink Wrap with Kangaroo Kangaroo [image] shrinkwrap_sharp.gh (24.2 KB) Here’s a go at this with the current Kangaroo, also using MeshEdit to make the convex hull to start with and Weaverbird. It’s still not perfect - edges that are part of the input geometry and the convex hull stay crisp, but it can still end up rounding other edges inside as it shrinks. I’d like to improve this, but I think it will need some slightly different way of finding the collisions, and/or remeshing while shrinking.

Thanks a lot Daniel. But I’m missing a few plugins again so will try once I installed them.

Hello everyone, I tried to make a mesh of my surface in a triangular net. I’ve read that it is possible with Grasshopper, but i have no idea how that plug-in for Rhino works. Could lease someone help me out? Thank you. best regards Christophe NewMeshine.3dm (4.4 MB) NewMeshine.gh (4.4 KB)

Are you after something like this? [image] remeshed_CF.3dm (358.0 KB)

Yes exactly. Thank you. But is it also possible to get regular triangles? I mean same size edges?

Any way to create a tape over objects?
