Well, I will accept your argument which appears to be quite understandable.

I think it should be saved into the current file. A new file might start with a default 0.001 value, then.

By the way, what happenes when you add the units? Will the default tolerance be altered properly if the units are changed from metric units to non-metric ones (so the "absolute" tolerance for both mm and inches will be the same) or the tolerance will remain? (0.001 units is 0.001 mm for mm or 0.0254 mm for inches; of course, 0.001 units is 1 mm for meters, but the mm and meters aren't "closely related" units.)
