Capping an organic shape so it can be used to boolean difference

Hi!
I’m trying to make a triangle shaped signet ring with an organic cutout that is also a triangle shape in the face. I’m using patch and a bunch of points and a triangle to attempt to make a shape that begins as a triangular prism and ends at the bottom as a sort of organic curve network. My issue is that this is producing a shape that’s hollow and uncappable so it can’t be used to produce the geometric triangle top that I’m looking for.

I’m not sure if this makes any sense, but here is a file so hopefully you can make sense of what I’m trying to do.
Triangle Signet.3dm (6.3 MB)

Thanks in advance for any help :slight_smile:

Hi! That’s the sort of thing I was after except cutting into the face instead of extruding out, preferably with some more bumps like a sort of triangle shaped hole. Do you think that’s possible?
