I’m wondering, say for example, I make two cubes, side by side, and select both and ctrl+J to make them one single object. Now how could I remove the vertices in the middle to make a simple rectangle with this? In simple, how can I simplify the geometry of an object WITHOUT losing the faces?
I understand I could just make a rectangle, but this is the simplest way I can explain what I am looking for. Basically a reverse knife tool
ve also tried selecting the four rectange corners and hitting f to make it a face, but beyond that, there are still the vertices in the middle.
