I drafted this timber framed truss with poly line solids, now I want to union them so I shift select all 4 beams and then hit the union key but only 2 will union. I can go back and select the now (3) objects and try to union the remaining and it will not do it. I also would like to work with poly line solids but I cant find poly line options in the X16. can anyone help me out? Thanks!
