Projecting a solid onto surface and subtracting method

Ella · May 17, 2018, 3:20am

Hi, all

I have several solids and projected them onto the surface as below.

I would like to subtract the solid area from the surface below.

For subtracting, I would like to make surfaces using these solids lines. but it doesn’t work.

Anyone who knows subtracting solid areas from the surface?

Why not just use the solids?
