Hi, I just made a sheet metal part where I added a sketched bend 1" away from both the top and the bottom.  When I go and check the flat pattern configuration in the model, and measure this dimension, it reads 1".  However, when I insert the flat pattern into a drawing and measure the lines, it reads 1.0055". The overall width of the part doesn't change, nor any of the other dimensions (if you add up all the intermediate numbers (11.6436"), it does not add up to the total width (11.6324").

What is going on?
