Constraing with planes

I am trying constrain two pieces of metal together but when I try to make the second constraint using the edges of the two piece’s planes I want the bottom of the one plane and I was wonder how I can do that? Right now I can only use the top of the edge, I want to use the bottom of the edge.

Thanks

I haven’t tested it recently, but I think you just select “flush” (one of the two buttons on the bottom-right of the constraints).

Yep, this should work if I’m understanding robolovR’s question correctly.
