I constantly switch between Unit Systems as the designs I work on integrate both metric and sae dimensions. I love Moi3Ds simple feature of the unit system being set to inches and being able to type a mm dimension in the window and for it to do the conversion.

Does jumping back and forth between unit systems on a file cause any kind of degradation of the dimensional accuracy? In other words is it a perfect conversion between units without rounding decimal points? I haven't noticed that it does, but I was curios how this is handled in Moi.

Thanks
