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