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
