Not sure if my explanation makes sense. I'm making a 3D model of the Titanic, and for most of the Smokestack piping I've been using the shrinkwrap modifier to attach curves to the smokestack, but the No. 3 Smokestack has piping that juts out to the Tank Room.
If I use the shrinkwrap modifier, the parts of the pipe that jut out will just stick to the smokestack. I could have the piping in two pieces (one shrinkwrapped the other not) but I was wondering if there was any way to have it all in one piece (maybe even learn a new way to have the piping sit on the curved surface).
