I am using the flexible tubing route feature in SolidWorks 2017. I create C points and have been auto routing between them. The routes look goods but as soon as exit the edit component feature the routes disappear. I can go back and re edit the route and the tubes show back up but I can never see them when I am at the top level assembly.
If anyone was wondering I found the answer to this. When creating the route there are two boxes to check - "use flexible hoses" and "save tubes as multibody parts." The "save tube as multibody parts" must be selected in order for the routes to show up when finished editing them (at least for my application).
