- Continue to use the design from the previous task or reload the Design7.pdes design.
- On the eCADSTAR PCB Editor ribbon, select Home > Design Rules > Rule Editor.
- In the Rule Editor dialog, Non Conductor tab, set the Symbol Mark – Hole field to "0.2000" if not currently set to this value, and click OK.

Figure 3: Cutting Back the Symbol Mark
- The symbol mark is cut back to avoid any obstacles as shown.
- A message is displayed when the operation is complete.
This task is demonstrated in the following video.
You have now cut back the symbol mark. Next, you will add dimension lines to your design.
