Design rules can be exported from, and imported to, the PCB Rules and Constraints Editor dialog. This allows you to save and load favorite rule definitions between different designs.
To export, right-click anywhere within the folder-tree pane of the dialog and select Export Rules from the pop-up menu. The Choose Design Rule Type dialog will appear. Select the rule types you wish to export and click OK . The Export Rules to File dialog will then appear, from where you can determine where, and under what name, the exported rules file (*.RUL) is to be stored.
To import, choose the Import Rules entry from the same right-click menu. The Choose Design Rule Type dialog will again appear. Select the rule types you wish to import and click OK . The Import File dialog will then appear, from where you can browse to and open, the particular PCB Rule file you wish to import.

Notes

Multiple rule types may be chosen for export or import using standard multi-select features ( CTRL + Click and SHIFT + Click). !worddav2efa9613aa2cc25c6eec075bc67f9978.png|height=1,width=368!When importing, if rules of a chosen type already exist, you will be asked if you wish to clear the existing rules prior to import. If you click Yes , all existing rules of that type will effectively be deleted and the rules in the .rul file then brought in. If you click No , the existing rules will remain. Note however that in this latter case, if existing rules and imported rules have the same name, the imported rules will overwrite the existing ones.
