Does anyone know of a good program for unbending tubes? I know about\nthe little trick using the sheet metal unfold command on a tube drawn\nsquare (with rounded corners), but i need something to work with more\ncomplicated tubes.\n\nWe punch all our holes in copper tubing before bending, and a nice\nflat view of where holes are located in the flat would be great. Right\nnow i add all of my holes in the bent up tube, then calculate what\nangle and location they need to be at in the flat. After this a new\nflat view has to be "drawn". I guess i'm getting spoiled by software\ndoing the calculating and orientation work for me, because all of this\nthinking makes me tired by the end of the day!
