In order to desribe how to fix the problem I need to see the wire frame of the model in that region.

The general idea is that you have to count the number of edges in the model surrounding the area you wish to place the hole (unsmoothed) and then split a circular ring of edges with a matching number of sides, connect the edges, and then extrude the inset and support edges.

In order for this to work and look correct you have to have sufficient mesh density around the circular inset. To little and you will get distortions, to much and your geo gets hard to manage.

Here is a guide...

This method demonstrates using a nurbs circle as a guide and using split polygon to draw in the edges.

Often I will simply boolean a cylinder into the side and then snap verts to the edges and cut in the diagonal edges with split polygon. In maya there usually several ways to approach every task.

The .ma file is at the bottom. Just remove the .txt at the end.
