I made a rectangular hole through a rectangular object. I now want to collapse all the little triangles that are formed into a single surface by selecting surface, and then using the Surface->combine feature. All is well for all but the last two surfaces int he plane. when I combine those two surfaces it looks like the 2 surfaces are erased and the interior portion of the two surfaces becomes a new surface. This is not what I wanted. Can someone explain what is happening and how to work around it?
