Project Mesh onto Surface

Hi, I’m looking for a way to project a mesh onto a surface. Ideally, I’d like find the projected surface area of the mesh at different angles, so it would be great if I could use this in Grasshopper.

:face_holding_back_tears: looking forward to some gh experts :exploding_head: my mind with this one :beers:

This sounds like a reverse-reverse-engineering workflow haha

usually the challenge is to project a surface onto a mesh. :slightly_smiling_face:

This is either very simple or very challenging (*). Get an Entry Level / indicative take (using a BrepFace - obvioulsy) :

(*) Imagine a “partially closed” Mesh (like the test Mesh) against a “partially closed” Brep … etc etc.

Thanks for your suggestions - what I ended up doing was using the native Project component in GH. This produced a mesh. Unfortunately, it was occasionally invalid, so I brought it back into Rhino, reduced the mesh by 50% and read it back into GH to get area information! Thanks!
