Ok, this is my first Sheet Metal part, and from the start it looks like it isn't using the basic features at all.

For some reason I just can't get it to work with Sheet Metal features only. I have a 3D wire frame that is fairly simple. There are some basic dimensions, but no dimensioned angles or lengths. This means I can't generate the edge flanges myself.

So to get some results, I drem it completly as a solid, and converted it to sheet metal. But I have to do some funky fixes and it still gives errors and strange cuts.

Can anybody point me out in how I have to design this thing the proper way?
