Talk to your fabricator first about measurements
Hi Bob
One thing I've learned the hard way is to confirm if measurements are inside or outside of the bend. Ask them how they indicate the difference on their drawings. I had one project bent up for me the whole thing was off either over or under by 1 or 2 thicknesses of the metal.
There are conventions for how to measure and draw for sheet metal drawings but I can't find my metalworking books right now, but the probably changed how they do it now anyway.
Let us know what you find out.
This thread has been interesting to me, years ago I paid a lot for a good CAD program which worked great until they kept changing operating systems on computers. Just because I expect a computer to last twenty years.
Cheers Phil
