The bounding box feature works great for flat sheet metal. Thickness, length, width. But if you have a sheet metal part that has a bend in it the Thickness, Length, Width are not the sheet metal values. It is the value of the box the part fits into. For example I have a bent plate that should have values of 3/8 x 12 x 2 but the bounding box is 2 x 5 x 7.5. Not useful.
So how do I get the sheet metal part values?
