Topic: Getting error 2722: Unknown work plane name with v13.5+ Technote 226 Date: October 2006 Product: All SmartCAM Applications Version: v13.5 and up Problem: Macros that used to work when referencing workplanes now fail with error 2722 Background: Due to work done on the variable system, the workplane referencing now, as it should have always been, uses a name or string value instead of a number. Looking ahead at many projects and proposals in SmartCAM requires tightening the rules of the use of variables in SmartCAM, and in particular the macro system. Solution: Use the WKPLN() function instead of the PLN() function In the past this would work: PROPERTY[ WP=PLN(#my_element) ] The WP parameter expects a name or string but the PLN() function returns an integer number. This will now fail. Instead use this: PROPERTY[ WP=WKPLN(#my_element) ] The WKPLN() function returns the workplane name. Please be aware the the WP parameter is used in other commands, for example: WITH_STEP[ ST=##, WP=WKPLN(#my_element), ... ]
