I'm using Solidworks 2010 and I'm trying to create a flat-pattern of a part.  I have the part in my hands as a prototype so I know it can be made and the model is accurate.  I do not know sheet metal well enough to get this flat-pattern to work.  The issue is the corners between the two bends.  I've tried more simplified models but this is the most accurate one.

If someone could help me configure the corner of a regular sheet metal bend series it would be greatly appreciated!

TIA  -  Bram
