I always cut from the file as in most cases every thing you need is there.
I might make stock and a few other things but I know 99% percent of the time I don't cheat the geo. I want the 3d solid model I will program it.I am used to making little complex parts. this way I can lay it out. PS I need the stock size you are using.
I will cut it and leave tabs you can pop the part off at the end.
