Please don’t waste people’s time by saying “Ctrl+M” and “Ctrl J,” this isn’t remotely like any of those. What I mean is this: Imagine you have two spheres and you just stick one part way inside the other. Those two shapes aren’t connected, blender still things they’re two shapes and they both have part of each other inside the other. Now, I know for a fact that it’s possible because I’ve done it before, there’s some kind of command or modifier that will merge those spheres into a SINGLE SURFACE with nothing inside, no intersection anymore and new vertices are made to treat both spheres like they’re one object that can’t be separated with L. Maybe it something to do with some boolean intersection or union modifier.
In my case, it’s not two spheres but rather a lot of extra surfaces from extruding, but I want vertices to be automatically created so there aren’t extra faces inside of each other and vertices are created where different levels are touching other faces.
