# Optimizing Face Count by Combining Faces

For demonstration purposes, let's say I'd like to minimize the number of faces for this object.

Obviously, there are countless ways I can join faces. There are countless combinations of rectangles I can combine to end up with the same shape.

I'm wondering, though, if there's an algorithm to find the best organization of shapes. An organization of rectangles that has the fewest number of faces possible while still maintaining the same shape.

This sort of stuff should be fairly common in modeling. Is there an "official" term for it?

• Could you clarify? I'm assuming ngon rectangles are ok, eg reducing above to a 3x4, 3x1, and two 1x1 single face ngon rects. – batFINGER Oct 30 '16 at 15:25

• Also note that minimizing amount of faces without worrying about Ngons is as easy as selecting all and pressing X > Limited Dissolve to convert the selection into a Ngon. – Mr Zak Oct 30 '16 at 11:18
