How Do I Change the Round Off Dimension in AutoCAD?

You can change the round-off value of dimensions in AutoCAD by modifying the dimension style. Here's how:

1. Open the Dimension Style Manager: Click the Home tab, then in the Annotation panel, click Dimension Style. You can also access this by typing DIMSTYLE and pressing Enter.

2. Select the Dimension Style: In the Dimension Style Manager, select the dimension style you want to modify from the list on the left. If you're using the current style, it will be highlighted.

3. Modify the Dimension Style: Click the Modify button. This opens the Modify Dimension Style dialog box.

4. Adjust Round-Off Value: In the Modify Dimension Style dialog box, go to the Primary Units tab. Under the Linear Dimensions section, find the Round off setting. Enter the desired round-off value. For example:

   • Entering 0.5 will round the dimension to the nearest half unit.
   • Entering 1.0 will round to the nearest whole unit.
   • Entering 0.0 or leaving it blank will display the dimension to the precision specified in the Precision setting.

5. Click OK and Close: Click OK to save the changes in the Modify Dimension Style dialog box. Then, click Close in the Dimension Style Manager to exit.

Now, any new dimensions created using the modified style will reflect the new round-off value. Existing dimensions will need to be updated (e.g., by using the DIMSTYLEUPDATE command or manually matching properties) to reflect the changes.
