Unary Rules presented in the Applicable Rules dialog.Unary Rules presented in the Applicable Rules dialog.

Summary

This dialog allows you to quickly access information about which unary design rules apply to the object currently under the cursor (selected or not). Unary rules apply to one object or each object in a set of objects. They have a single rule scope.

Access

Access this dialog in one of the following ways:

  • Right-click over a placed design object in the workspace (the object can be selected or not) and use the Applicable Unary Rules command from the context menu.
  • Without any object selected, right-click in the workspace away from any objects, and use the Applicable Unary Rules command from the context menu. You will be prompted to select an object in the design. Position the cursor over the required object then click or press Enter.

Options/Controls

  • Unary Rules List - the main area of the dialog confirms the design object being 'interrogated', and lists all defined design rules, by rule type, that could be applied to that object. The specific constraints for each rule are also displayed. Each rule will have either a tick () or a cross () next to it. A tick indicates that this is the rule with the highest priority out of all applicable rules of the same type, and is the rule currently applied. Lower priority rules of the same type are listed with a cross next to them, indicating that they are applicable but, as they are not the highest priority rule, they are not currently applied. Any rules that would apply to the object but are currently disabled also have a cross next to them, and are shown using strike-through highlighting.
  • Design Rules - this button becomes available when a rule entry is selected in the main list. Click it to access the PCB Rules and Constraints Editor dialog.

Tips

  1. If, rather than seeing which rules apply to an object, you would prefer to pick a rule and see which objects that rule applies to, this can be achieved from the PCB Rules And Violations panel. As you click on a specific rule in the Rules region of the panel, filtering will be applied, using the rule as the scope of the filter. Only those design objects that fall under the scope of the rule will be filtered, the visual result of which (in the main workspace) is determined by the highlighting options enabled (Mask/Dim/Normal, Select, Zoom).
