2D intersection with 3D.

I currently could use a function that would return a 2D object from the intersection of a 3D object and a 2D object.

For my application, 2D object which is the shadow of a 3D object on a plane would also work.

Alternatively if linear_extrude() could use a 3D object instead of a 2D object, that would also work.

So far, I have not yet been able to figure out a solution to achieve any of those.

I think what you want is to enclose your 3D object in projection(cut = true), then intersect that projection with your 2D object.

That is exactly what I was looking for. I don't know why I did not see it on the cheat sheet.

Thanks.
