VARIABLE/FUNCTION - Use current valor?

[mathieubrassard1987]

Sorry for terribly wording my question this thread is exactly what I tried to do;

The function of checking the existence of the parent attribute

I tried this plugin: if defined?($dc_observers) # Open SketchUp's Dynamic Component Functions (V1) class. # only if DC extension is active class DCFunctionsV1 protected # return 1 if exist and 0 if not # Usage: = framing_exist() def framing_exist(a_value) if (defined?(a_value)).nil? return 1 else return 0 end#if end protected:framing_exist end#class end#if error: unknown function [2019-01-10_21-58-22]
