Dimension Style Override Unresponsive

[mlars010]

Hello,

I am using AutoCAD Mechanical 2012 (Student Edition) and need to override my base dimension style settings to include tolerances on drawings.

The program seems to disregard anything I do with regard to overriding the dimension style settings.  The specific tolerane desired in this example is (Upper: +0.021; Lower: 0) but I need both numbers to display to three decimals.

Here's how things look at my end:

1. Create dimensions using my preferred generic settings
2. 'DDIM' -> Dimension Style Manager
3. Select current style, 'Override'
4. Override Current Style window > Tolerances tab > Tolerance Format area > Precision: '0.000' (base setting is '0');  Method: 'Limits';  Enter appopriate Upper value and Lower value
5. Preview window updates correctly for all changes
6. 'OK'
7. Dimension Style Manager: Preview of: <style overrides> still displays correctly
8. Close Dimension Style Manager window
9. Annotate tab: Dimension panel: Update Dimension
10. Select object(s), press 'return' on keyboard
11. Nohing happens - selected dimension has no tolerance and remains at original precision
12. 'DDIM' -> Dimension Style Manager
13. <style overrides> sill selected and Preview still looks correct (3 decimal places)
14. 'Modify'
15. Precision drop-down is reset to '0'

(Note: Skipping from 5 to 14 gives the same response.)

Here is what the command prompt returns for the Update Dimension command:

• Current dimension style: ASME     Annotative: Yes
• Current dimension overrides:
•   DIMLIM         ON
•   DIMTDEC      3
•   DIMTOLJ       1
•   DIMTP           0
•   DIMTZIN        0
• Enter a dimension style option
• [ ANnotative/Save/Restore/STatus/Variables/Apply/? ] <Restore>: _apply
• Select objects:

The formatting options in the Power Dimensioning tab don't allow me to show redundant zeroes (e.g. 25.000) so I cannot use that method regardless of the DIMTZIN value.  The rest I have already described.  Can anyone help me with this?

Hi,

Can you uncheck " Trailing" option in DDIM>>Select the base dimenesion style>>Modify>>Primary units tab>>Zero Suppression>>Uncheck " Trailing" and verify the issue.

Repeat the above step for Tolerance tab too.

Try creating a new powerdim and enable the tolerance button.

Thanks

Please find attached sample drawing too.

I've been able to fix this issue by going to AMOPTIONS>Standards>Dimension Settings and setting my custom dimension style as the "Base dimension style" while leaving "Force power dimensions to use this dimension style" selected.   I can now obtain a dimension that looks like:

6.0000

5.0079

Previously I was unable to force trailing zeroes to show, regardless of options being de-selected in the DDIM window tabs.
