i have a bug in my model and hope to find some bright brains to give me a lead in here. 

I made a model driven by plane and sketches so that i can manipulate all dimensjons from Drive Works.

Down in the square corner, where all bends meet, i need at cut from plan and thru all. Managed to make a plan connected on sketches and it works, but....

The cut need to be 5mm in width, and have "Optimize Geometry" on. In some instances the model wont fold out correctly because of this cut .

In the model attached, this cut is 0,3mm. Anny one have any good solutions for me?
