I don't know how to explain it any better than it's explained in the help file. If it didn't do quite what you wanted you'll need to be more specific about exactly what you want to do.
Dude,stfu ... Stop talking smack about me until u prove to me that you can script. And I meant,drawing like colored 3d objects .. Like the "3d stuff" from picwin.tk.
If you want something from picwin.tk, you should probably check the code used by picwin.tk. Otherwise your best bet is to read the /help for the draw commands and figure out how you can use it the way you want instead of complaining it doesnt do what you want-- without knowing what you "want", no one here can help you.
