Adjusting tolerances in Autocad®.

After clicking on the ‘Modify…’ button, click on the ‘Tolerances’ section as shown by the green box above from appeared window. As you see above, you can adjust the format of tolerances as shown by the green arrow;

  • Symmetrical: This is generally used tolerance style in most technical drawings. You can not give a different value for upper and lower tolerances.
  • Deviation: The upper and lower tolerances as shown in separate values. You can give different upper and lower tolerance values.
  • Limits: If you select this one, the upper and lower limit value of dimensions separately shown. Not tolerance values itself.

From the precision section, you can adjust the digit number after comma up to 8 decimal numbers as shown by the red arrow above..

‘Scaling For Height’ option adjusts the height of tolerance number in dimensions with scale factor according to the height of primary dimensions.

You can adjust the placement of tolerance and zero suppression of your tolerance values as shown in the orange box. For example, your tolerance dimension is 0.005, if you select the ‘Leading’ option, this value will be suppressed as .005. If you select the ‘Trailing’ option, 0.05000 will be suppressed as 0.05.

Like alternate units for primary dimensions, you can also adjust alternate tolerance units as shown in a red box above.

Click ‘OK’ to save your adjustments in Autocad® tolerances.
