(Atom 3D V21) In the attached design if you zoom in on the corner where I have Sketch<9> and Revolution<9> and then Edit Revolution<9> I think you will see what I'm trying to do which is to fill the corner. On top of that surface I was going to place a little circle and extrude it upwards as a registration point for a part that will go on top of everything. I was going to do this in each corner. When editing the Revolution it looks like it will work but when I exit and view the model it doesn't work. Am I doing it the right way incorrectly or am I doing it the wrong way?
