If you change the material you change the percentage.

Dimension sheet metal to inside or outside. Only the truly critical dimensions should be highlighted as such. And also find you fold centers more easily. 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. Hem measurement forming hems is one of those aspects of sheet metal that is very operator dependent.

It is one of the main and basic forms of metal working. The greatest feature of sheet metal is that it s having ability to be formed and shaped by no of process.

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.

This means that outer radius will be inner plus thickness. My boss dimensions from outside the flange walls and thinks this is the.
