Good Morning Everyone,

I'm trying to convert a mitered pipe segment piece into a sheet metal part that can be flattened then plasma-cut and rolled.  The shop drawing calls for small sections of pipe to be cut width-wise then mitered both ways (see attachment).  I'm thinking it may be easier if these pieces can just be burned out of 3/8" steel plate then rolled (may have to stitch-cut along the curve to facilitate in rolling).  I tried using both "convert to sheet metal" and "insert bends" but I don't think either will work since there is no straight edge to start from.  Any ideas if this is possible?  I'm thinking I may have to make the piece longer to have straight edges and then treat it kind of like a rolled cylinder.  I think the best case scenario for me would be to roll a plate into a cylinder a little wider than the finished piece and scribe the handburn lines on the plate to be cut after rolling.  I've attached a few screenshots as well as the part file.  Thanks for any advice.
