I do not currently use the BOM functionality of swx. Recent improvements are making me rethink BOM's on my drawings. A Limitation that I am finding is the ability to calculate a stock size. For finished size I am able to define two sketches and move them to the end of the feature tree to get my finished size. This file is available upon request. I would like to take the three dimensions that define x,y,z and add a preset amount to them. For instance "z+.02" or "z*1.02". Currently I cannot find a way to set a variable to do this calculation. For every part I must calculate stock size. Can anyone shed some light on how I can do this (without excel formulas) Bama
