The Choose Design Rule Type dialog
The Choose Design Rule Type dialog


Depending on the way in which it is accessed, this dialog is used to:

  • Specify one or more rule types to be exported into a .Rul file from the currently defined set of design rules for the board.
  • Specify one or more rule types to be imported from a .Rul file, into the set of design rules currently defined for the board.
  • Specify the type of rule to be used when adding a parameter as a rule to a supported design object in the schematic domain or a schematic document.
For more information about PCB Design Rules, click here.


The dialog can be accessed in the following ways:

  • From the PCB Editor - right-click in the left-hand pane of the PCB Rules and Constraints Editor dialog (Design » Rules) then choose either the Export Rules or Import Rules command, depending on whether you are wanting to export or import rules.
  • From the Schematic Editor - in the Properties panel in Parameter Set mode (double-click on a placed Parameter Set in the design space or right-click on a placed Parameter Set then select Properties), click the Add button then select Rule from the drop-down.


The dialog lists all rule types, grouped by parent rule category. Simply select the required rule type (or multiple types when exporting/importing) then click OK.

When exporting selected rule types, clicking OK will access the Export Rules to File dialog in which you can define where and under what name the resulting rule file (*.Rul) is to be saved. When importing selected rule types, clicking OK will access the Import File dialog in which you can browse to and open the required rule file (*.Rul).
When adding a parameter as a rule, clicking OK will open the Edit PCB Rule (From Schematic) dialog in which you can define the constraints specific to the chosen rule type.
