If you take a look at the screen capture below:
You will see that the top face has been subdivided without extra edges being created on the sides of the cube. I selected the face then e to exrude then i changed my mind and hit esc-key. Without removing doubles i selected w-key and sudivided once.
To my supprise the image above was created. Then i removed vertices and the subdivided faces remained. Is this legit ? Can anybody explain why the “normal” extra edges were not created this time.
BTW i’m using the cvs build by gabio.
