grrrr dimension tolerances!

David Janes

rel. 2001- build 2003010; metric units; working in the drawing of a part. This applies to both 'created' and 'shown' dimensions.

My default decimal places is 2. If I right click the dimension and click properties it opens the dimension dialogue box. If I change a tolerance value from the default +/-0.30 to say +/- 0.10, then I decide afterwards to alter the decimal places of the dimension from 2 to 1, the tolerance value does not change to +/-0.1 as one would expect, but reverts to +/-0.3. This could lead to tolerances being modified by ProEngineer unexpectedly.

Imagine if you have laid out a drawing, calculated and entered all your tolerances, then you decide to alter the decimal places of many dimensions all at once? They will all change back to default values, and you will have to recalculate and edit them all. Even worse, you may not notice the changes and release the drawing with the wrong tolerances.
