To modify grid spacing in your work frame:

1. In the No. of Grids field, enter the number of grid lines you want to use.
2. In the Total field, enter the total length of the work frame dimension.
3. Uncheck the box in front of Length, Width, or Height. Unchecking the box allows you to manually enter the distance between grid lines, rather than using uniform spacing.
4. In the dropdown list to the right of No of Grids, click and select the desired grid line. For example, select XGrid4 to adjust the spacing of the X axis grid line labeled 4.
5. Type an alternate distance value and press <Enter>. The work frame updates automatically based on your changes.
6. Repeat to select and set up additional grid lines.
7. Select the OK tool .
