Troubleshooting Small Dimensions

If the dimensions appear too small after the adjustment, consider the following steps:

Ensuring Visibility of Dimensions

If dimensions are not displaying properly:

2. If the dimension lines are visible but the text is not, verify that the text style size is appropriate for the scale of the drawing.
