Or, install Zorro2, make a section plane and right click / slice at section: no clean up.

Great plugin! Thanks!

I am trying to trim off the corrugated sheet metal wall of a shack. I put in a plane that divides the two pieces, one of which is to be trimmed off. I have tried to figure out how to do it but failed. I can't use the solid tools because the wall is not a solid, it says.

How do I do this?
