I’m trying to build a traditional hearth and chimney structure, and for the most part, it’s good, but there’s one piece that won’t fit because it doesn’t snap to the bottom of a ramp to overhang like an exhaust hood. This is my first post, so I can’t upload the picture to make my suggestion more clear. So here’s a rough representation.
/ | is supposed
/ | to be a
/___| right triangle
There is a ramp piece on the hypotenuse of this triangle and a wall piece on the right. There is nothing on the bottom. The right angle piece exists, but it doesn’t snap in that corner without something beneath it.
