Extract contour curves from multiple polysurfaces

Hello All,

I’m looking to find a way to extract all the ‘countourlines’ of the polysurfaces out the Bench (see attachement). is there a way to get these contours layed out on the XY plane? Also i want to have them linked with the Bench created in Grasshopper so their ‘Contourlines’ changes with the model.

Any help would be welcome, as i don’t have much expirience in grasshopper yet.


Hello sailor!

A simple deconstruct brep followed by a move would do the trick.

If you upload your file I can take a look.

Also, if this is for laser cutting, I would recommend to take a look to rhino nest.
