Okay, I'm a little confused. Can that default precision be changed, or is that built in to the program? It's not too unusual to encounter machining tolerances of 0.0005" (very good machinists, of course). Can I not work down at that level with MoI?
Also, if I perform the operation on the 10X version, can I then scale it back down to the original size?
