Overlap
The overlap rule is used to ensure that one item overlaps another by a minimum amount. For example,
a transition area must overlap a zone boundary by 2.54mm.
To enable an Overlap rule:
1. Select the TRANSITION_ZONE and ZONE_OUTLINE subclasses.
2. Select the rule type as Overlap.
3. Define the overlap value.
4. Assign a DRC label. For example, choose "T" for Transition.
5. Assign the DRC Display Layer.
D efinin g an Ov erla p Rul e
When the user adds a transition area geometry and violates the overlap rule, a DRC marker is displayed
indicating the overlap value has not been met.
