This is a bit of a terminology thing. If you’ve never worked in 3D computer graphics before, you might expect that a join operation on two objects would result in a single, connected mesh. That’s not quite how it works. Earlier in this chapter, I explain that an object can consist of both linked and unlinked elements. There’s no requirement that, for example, all the vertices in a mesh object are linked by faces and edges. When you join two separate objects using Object ⇒ Join, you’re really just bundling them into the same object datablock. You aren’t changing any of the component mesh data.

To actually merge meshes into a single linked unit, you need to either

 Edit the mesh data manually — merging vertices and creating new edges and faces as necessary.

 Use a Boolean — an operation that does a logical (for example, and, or, intersection) combination of two meshes.In Blender, Booleans are done with a modifier. Modifiers are covered in more detail in Chapter 5.
