My objects are all base on aspect ratios. 1:1 1:2 etc. When I select Maintain width and height proportions, the do not chang evenly. for example I have a 1:1 150 mm square rectangle. With "Maintain width and height proportions" selected and I change the width to 140 mm the height changes to 139.993 mm. How do I fix this?
That seems a normal way to get as close to 140 as makes no difference. Five significant figures is close enough. Adobe added more decimal places to display at some point, and it seems to have led to a lot of non-problems.
