How to cut a hole in a subdivided mesh? Without actually applying the subdivision modifier, how can we cut a hole through the subdivided mesh? I tried using loop cuts but the topology turned out bad:


Using the boolean modifier it had some artifacts and you also need to apply the modifier:


Further trying to fix them with loop cuts gave this strange edges:


and scaling them along the y axis to zero did no good. So How can we cut a hole through a subdivisioned mesh without actually applying the modifiers? I know disabling the boolean modifier would give a nice hole in the render but what if we have to do some editing with the part, like adding a drawer object(particularly in this case)?
You can use the Inset tool. That way you can keep the topology as quads.

Select the faces where you need the cut, press I to activate the inset tool, and then by dragging the mouse you can determine the size of the hole.

After just extrude (E) and delete the faces as needed.
