I'm trying to self-educate myself on tube routing and I think I got in over my head. The tutorial videos make routing look very easy...when all the templates & fittings are setup. I'm working from scratch. I just want to run a pipe route and am experiencing nothing but problems. I finally managed to get a 3D route from one fitting to the other but as soon as I exit the 3Dsketch, the route disappears. As is usually the case, I'm probably not doing something correct. Any help would be greatly appreciated!
