Having a problem with routing and flexible tubes.
I opened an assembly today and all my tubes were gone. All routing assemblies with tubes showed red/rebuild errors.
If I edit a route, the tube shows up in the preview. When I accept the sketch, the tube disappears again.
No amount of rebuilds, close/open, restarts fixes it.
Any ideas??
In the routing library manager make sure that your routing template is an actual route assembly template.
