Well, if I supply a String as an option, it would get compiled in with the rest of the script. Thus, you could make the string "True" or "-1836872", but also "New OnCircle(New OnPlane(), 30.0)" Sounds like the least work for me and the most flexibility for you.
Of course it also places a lot of responsibility on you since you should not type in something that won't compile, but if you're already a scripter, I think I can trust you with some default values... -- David Rutten [email protected] Robert McNeel & Associates On Jan 16, 3:41 pm, damien_alomar <[email protected]> wrote: > Thanks David...no need to make GH vulnerable as there's plenty out > there who might shoot themselves in the foot trying to play with it > (myself included).
