I've tried to find a thread that covers this question, but I can't seem to find one. My question is if I create a line based family and the shape of said family is round, like a round duct, how can I get it to miter at the corners? The family seems to be working great except where I turn a corner. Ideally I'd like to be able to make any angle I want and have the corners clean up automatically. Any help is appreciated.
