Wrapping fillet box with using kangaroo

[11194 (Shimpei)]

Hi

I want to make mesh model that wrap fillet box.
To draw shrink expression, kangaroo is suitable tool I think.

First picture is wrapper.
Second picture is fillet box that will be wrapped.
Third picture is wrapper asumed shrinking image.

Shrink Wrap with 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.

I tried and modify above .gh file but I could’nt do what I want (specifically sticking fillet edge)

Can anyone help me?

Best,
Shimpei

Hi Shimpei,

Here’s how I’d set this up

I found I needed to add a symmetry constraint, otherwise it tends to slip round so the openings move to opposite corners:
