Hey Im new in blender and I'm having what appears to be a simple problem, why cant I dissolve this edge? I made a plane and I loop cut it to make the hole in the middle I dissolved the other edges except for these two

I cant dissolve the two selected edges

    $\begingroup$ because you need at least one edge that connects the outer quad to the inner one $\endgroup$

    $\begingroup$ I'll add that the preferential placement in this case would be an edge connecting the inner and outer edge loops at each corner $\endgroup$ Jun 12, 2021 at 21:07

Faces cannot have holes in them in blender like they can in sketchup. This is because blender is closer to the hard coding of 3-D graphics.

    $\begingroup$ @sol_keys At the base of 3-D graphics, faces are always triangular. Blender allows you to create polygons by triangulating them at the last minute before sending the data into a render engine. $\endgroup$
