Using Squish command from Grasshopper

[PetcuDaniel]

Hello,
There is an old thread who is discussing this problem ( https://www.grasshopper3d.com/forum/topics/using-squish-from-rhino-with-a-c-vb-or-python-component?id=2985220%3ATopic%3A1134820&page=2 ) but I don’t know why is not working in my case too (a half of a shoe last and upper’s curves!
I’ve attached an example of the shape and curves to be squish!
Maybe @djordje could give me a help!
Thanks in advance!

what happened with this?

good job finding that!

@PetcuDaniel

I don’t know why is not working in my case too

because squish needs a 3-D surface or mesh - your object is a polysurface

same story LoL

when your shape is a surface, the python from @djordje works.

Here’s one way to turn it back into an untrimmed surface,
though I still suggest you model it as a surface from the start

Hi @corellaman! Nice to ‘see’ you again - give me hope!
As you can see from the picture I’ve to delete what I’ve added to your solution even if that solution theoretically is the best ! There are a couple of reasons:
1- there are some last’s shapes for which that solution doesn’t work (I’ll show you which one)
2-the automated generated patterns are not nice and continuous because the 3Dcurves are not Ok when flattened to 2D! Sure with some algorithms it could work but I don’t have the time now to develop this and I’m not so smart - Lol (for the last quality seems that McNeel forum compensate very well!)
3-As I’m trying to work with unusual foot shapes I need to have more alternatives for flattening including the one to obtain it manually, digitize it and then generating 2D patterns in Grasshopper!

Ok, I’ve seen this but the polysurfaces are the result of baking the 2 half surfaces generated at the starting of your code and I can Squish them directly in Rhino! To me if I can squish them directly in Rhino then it should work with the @djordje work! But it is obvious it is something which I don’t understand!

Thanks! I’ll try it!

Ok, I’ve tried it!
But what about the curves on 3D surface? This are upper’s pieces borders and needs to be squished also!
