Hi, I'm making a car for a uni group project and i need to join the base of the car with the top part that my friend made. I want them to remain in subds of course, and not become nurbs surfaces. It's the first time that I use Subds so I don't really know if there's a command or a tool to do what i need, and by searching on the internet i didn't really find what i was looking for.
