Is there any way to use where two layers intersect in an expression?
For example, two layers in 3D space. One is rotated 90 degrees on its Y axis, the other 90 degrees on its X axis, like a standing wall and a flat surface. If the flat surface rotates from its anchor point in its center, is there a way to use where that layer intersects with the wall as it rotates?
Theoretically, I think you could calculate the intersecting line of two 3D layers, but I think you'd be entering the realm of some pretty serious 3D math. It might not be practical for expressions. I'd love to see it if it exists, but I know I don't have anything like that lying around.

I figured this might be the case.
I'm trying to make a 3D culture flask with liquid that sort of adheres to gravity (as in you tilt the flask and the liquid remains level) Normally I'd just animate this by hand and be done with it. But I'm building this and other stuff for scientists who aren't good at animating but want good looking and practical assets.
