Hello. I am trying to place "cables" down the side of a pipe and through a couple different ports. The only way I've been able to successfully sketch lines to follow through these spaces is with 3D sketch, but I can't figure out how to make those lines solid and have a circumference, etc. I can only make them solid with 2D line sketch and sweep, but the problem with that is I can't get the lines to travel across XYZ axis. Only XY and that just won't do it. Even when I try to make them flexible parts. Please help and thanks.
