Hello friends. I just started to get acquainted and learn Python Script, hope you guys can help me answer this problem. I try to draw line from Autocad Layer, for example i have 3 shapes with layer name 0, when i draw line from layer 0 this can only make 1 shape, is there any way i can draw line for 3 shapes is the class name 0 or not? Hope you can help. Thanks very much

Why don’t you use BimorphNodes?
