Driven Dimensions

I cannot find how to control the trailing zeros of driven dimensions in the 3D model. I would like to adjust the number of digits of dimensions in accordance with my tolerance block. Since I'm trying model base definition, I need to do this in the 3D model. Any clue?

You can adjust the number of digits by selecting the dimensions or annotion elements and RMB>Properties. As best I can tell trailing zeros are controlled by standard and is going to depend on the unit system. English units will show trailing zeros, metric units only show trailing zeros when appropriate on dimensions shown as limits.

All my options are set to 3 decimal places. All my dims are also set to 3 decial places. Sadly the trailing zeros don't shows up. What I understand is that we cannot control it, is that right? I have to show tolerances seperately on each dimensions?

Not directly as far as I can tell. In part mode the display of trailing zeros seems to be controlled by the unit system used and by standard. If you are using a metric unit system (which I assume by your description of what is happening) trailing zeros only show if you show toleranced dimensions where there is an unequal tolerance. So if you have dimension values of 20 and 25.5 millimeters trailing zeros will not show because by standard trailing zeros are not used with metric dimensions even though you have set the model to three decimal places. The exception is where you show dimensions that have an unequal tolerance. So if you had a dimension of 25 millimeters with +0.1 and -0.05 tolerance values and you used three decimal places in your model your dimension would show as 25 (with no trailing zeros), +0.10 (trailing zero added), and -0.05 (with no trailing zeros) if you show it as plus-minus even though you set the model to three decimal places. If you displayed the dimension as limits you would get 25.10 (trailing zero added) and 24.95 (no trailing zeros). English units should show trailing zeros up to the number of decimal places used.
