I have a model of a power pole (for model trains) I was drawing up, and as an exercise I was trying to modle the wires that interconnect on it. I created a 3D sketch in the assembly, but I cannot figure out to make a part of it. If I try "add Part" I cannot 3D sketch in it, if I 3D sketch in the assembly, I cannot create feature. I added a small circle to the end of it to try and sweep it, but there is no way to do it....any ideas? thanks in advance....
