I've opened this post here thanks to a quick chat with @CGBenner. He proposed to also tag the QA-team @johnsonshiue and @ChrisMitchell01.
Even if it's just sporadic, I've encountered this behaviour just once (in the attached file), I think it's worthwhile reporting.
I've started playing around with the tolerance feature in a simple file made for 3d-printing. As you can see in the screenshot the inner two edge's lengths are toleranced, while the 4mm width is not. For dim 30 -0.05/-0.1 the 'Evaluate Size'/ 'Upper'-setting is activated. The correct calculation should be (30mm-0.05mm)+2*4mm=37.95mm. Using AIP's measuring tool, this value comes out correctly.
For reasons I've now placed a driven dim at the two vertices of the left short inner edge and it _in_correctly shows 38.025mm, a delta of 0,075mm. A second driven dim attached to the two edges again shows the correct value.
If I delete the wrong dim and set a new driven one, I can not repeat the wrong number.
Nevertheless - it's persistent in the part and in the parameters in this file version and is definetely something that should not occur.
Best, Lars.
