True, but he's looking at affecting the display of driving dimensions for geometry. Since the curves don't drive the solid any delta means the dimensions on the drawing don't match the model.
Letting rounding affect the appearance of dimensions on drawings without identifying them as inaccurate was a foolish move by PTC. I'm sure it was a customer request, but it should only be turned on by hidden config option.
For example, 2.5 rounded to no decimal places is 3. If it's not exact within the limits of precision of the software, any rounding like that should only be displayed as ~3 or 3 to make it obvious there is a discrepancy between the geometry and the dimension. I'm sure the programmers would not like it if their accountants altered the paychecks to not match what the actual direct deposit; why would they think this is a good idea (besides being told by management)?
