I've seen this quite a few times and it's giving me a complex I'll measure a part (No CAD model) a simple plane line line alignment. Then I'll measure lines for a simple distance check from my origin. The problem I'm seeing is the dimension call out are 2 place callouts and some 3 place callouts so I have eveything defaulted to show 3 places. After measurements are taken I go back in and edit the nominal to what the print calls out but when I pull up the report the nominal is not what I edited it as e.g. nominal entered as 80.36 +/-.06 on the report it shows up as nominal 80.366. Some show higher then the entered nominal some show lower.
