I’ve had this problem quite a few times now.
I’d like to create a 3d-rectangle and divide the front and back faces but not the sides, or at least no more than necessary. At the moment i can tell Blender to sub-divide a cube and it does that very well, problem is the program also creates little sub-divisions along the sides of the rectangle.
I’m sure i’m just being stupid. There must be a way you can do that, but at the moment i have to manage without it because i can’t find it.
