You're passing one argument, a list contaning 3 elements, instead of 3 arguments. Try this (by the way, you can omit nth call):
(.SetOrigin cone (v 0) (v 2) (v 3)) Another option (not really relevant in this particular case) is to use memfn: (apply (memfn SetOrigin) cone [2 4 6]) суббота, 23 июня 2012 г., 15:33:23 UTC+6 пользователь Antonio Recio написал: > > I have an object called cone.
