I noticed an issue with 2012 dealing with spin box increment/decrement. I currently use 3 decimal place numbers for my design work. My spin box increments are set to 0.0625". When I increment up and then back down, or down and then back up I end up with a rounding error. For instance, if I start with a dimension of 0.125" and deccrement down I get 0.063" and then I increment up I get 0.0126" instead of the original 0.125". SW 2011 and prior did not do this. I can change my units to 5 decimal places and the error does not appear, but I don't want to send projects to my machine shop showing 5 decimal places of accuracy. Any ideas?
