Mesh intersection

Questions

Hi guys,

I ask for your help yet again.
I built this simple example to help explain my needs:

What I’m trying to to is, through maybe CSG, remove everything but the part of the plane that has intersected the box.

So looking at this image, I guess what I need is only the blue part of a subtract or an intersect.

Is something like this possible? It’s not a necessity to stick to CSG, as long as I can attach a simple material to it.

Any help is greatly appreciated.

You can try to use a thin box instead of the plane and take the intersection of both planes:

Thank you for your input. Here’s an update on this.

If I change the plane (or box as in your example) this doesn’t work anymore. This is actually what I’m trying to cut here, I added a plane in the example to make it easier to follow.

From my understanding, if I can manage to add the 0.01 in thinkness to the corrugated plane, then it would be fine (the thickness in the end result doesn’t bother me), but I’m unsure if I can extrude the mesh further, on the y axis.
