We’re introducing two new algorithms for the _Squish command that offer more control and robustness compared to the original implementation. Like before, these methods flatten a 3D mesh into 2D by minimizing distortion, but now with enhanced physical realism. The new solvers account for orthotropic…

What’s the easiest way to run these commands with geometry from grasshopper?

@Akash Thanks for all your questions! I hope the following helps: These new algorithms are only modeling membrane stresses (i.e. assume that bending forces are 0), so varying the thickness would only change the external forces applied to reach the 3d shape from the 2d pattern, and would only change…

@martinsiegrist No Grasshopper integration yet, your best way forward is to bake everything and run the command in Rhino (or script the baking and command calling from GH, as is often done for the many Rhino-only commands). What workflow were you thinking about or would use as a first solution? Hav…

I haven’t used Shapemap. Will try to bake and run it in Rhino…

I compared the new flattening method with a handmade flattening, made with wrinkled paper, a method that I am used to for flattening shoelasts for pattern design of uppers. Both methods come close as for the results, it is already much better than the older Squish. I first applied Quadremesh on d…

These squish commands are looking promising. But how can we flatten details on the mesh with it?

@smpeter @pierrec Great to see better flattening being added to Rhino! Any chance this could work for flattening shoe upper shoemaking patterns (from 3D shoe last to flattened pattern like the one below)? [image]

[image] smpeter: _TestSquishPhysicalStrain Just been testing it out now. It only works with meshes? It runs very slow, and not getting very good results. I was getting better results with an earlier version of ShapeMap but oddly worse in the latest edition. It would be great to see ShapeMap …

It didn’t quite yet make it fully into Rhino, but ShapeMap is now distributed with Rhino WIP as a Grasshopper plugin. And it runs on Mac and Windows now!
