How to merge 4 adjacent, coplanar faces into a single face

Question

I have a plane consisting of 4 squares - take as an example a subdivided plane. How can I merge these faces into one?

Dissolve the middle vertecis of each edge and the middle vertex, by pressing [x]> Dissolve vertices — someonewithpc, Dec 14 '14 at 17:19

There is an operator called Dissolve which does exactly what you want.

Select everything, with A, and then press X (or Delete) and select Limited dissolve. This will do the same thing as above, but will not require you to select the proper vertices manually.

so long as the faces are surrounded by more geometry, using f for Make Edge/Face works well. For a whole simple sub-divided plane like the example given, this tool will make a mess.

This does recuce reduce the poly-count (check the triangle count in the header) – ideasman42 Dec 14 '14 at 22:46

I found that it is sometime more efficient to use x in edit mode then Disolve edge.

Let's convert this curve into mesh with ALT+ C:

You end up with the following mesh.

This mesh will be hard to process because it has holes. for example, f simply doesn't work. Using Limited disolve will not work well too, here is the best result I can get using this method :

Disolve edge is interesting because you can process the mesh multiple times without changing the whole shape. Here is the result I obtain after two Disolve Edge :
