Default constraints for the Component Orientations rule.
- Allowed Orientations– the chosen orientations that are made available for use by the Cluster Placer. The following orientation-based options are available:
- 0 Degrees – allows the Autoplacer to rotate a component to the 0° orientation.
- 90 Degrees – allows the Autoplacer to rotate a component to the 90° orientation.
- 180 Degrees – allows the Autoplacer to rotate a component to the 180° orientation.
- 270 Degrees – allows the Autoplacer to rotate a component to the 270° orientation.
- All Orientations – allows the Autoplacer to rotate a component to any of the four individual orientations.
How Duplicate Rule Contentions are Resolved Copy Link Copied
All rules are resolved by the priority setting. The system goes through the rules from highest to lowest priority and picks the first one whose scope expression matches the object(s) being checked.
Rule Application Copy Link Copied
