Your manufacturer may not be able to match dimensions when creating the actual sheet metal part due to tooling and equipment limitations. I think this is the better way because you can acquire your cutting length without a flat pattern by adding the inside lengths fold allowance. If you change the material you change the percentage. This means that outer radius will be inner plus thickness.

Speaking of sheet metal tool you can not control both the radius directly and more over sheet metal modelling assumes that thickness is uniform. My boss dimensions from outside the flange walls and thinks this is the. When producing drawings of sheet metal components i dimension from inside the flange walls. Only the truly critical dimensions should be highlighted as such.

Subtract the osos from the edge to apex dimension called on the print and you ll find exactly what the edge to outside radius dimension should be. Neutral axis the location in the sheet that is neither stretched nor compressed and therefore remains at a constant length. Since each metal fabricator has its own tooling bend factors and equipment to develop the flat blank it is better to fully dimension to formed views for that manufacturer.
