Good Morning,

Looking for a little bit of help.  I was given a model of a flow control hood that needs to be re-fabricated.  After asking a question on here last week about how to actually sheet metal some of these pieces, I did a surface flatten and then converted that surface into a sheet metal body.  The issue I'm having now is how to tell the fabricator the roll radius of the corner pieces of this weldment.  The back piece was easily defined with a section cut and a radius dimension.  I'm going to upload the part itself as a Solidworks part file and a STEP file and I've also included a screenshot with arrows to the pieces I'm talking about just for clarity.  We are currently using Solidworks 2020 SP3. 

Any help would be greatly appreciated.
