Exporting a shape made out of quads results in hexagons in obj file I made some sort of furniture by taking the default cube and insetting some parts of it and splitting(subdividing) it here and there. Then I add a bevel modifier with 1 segment.
A view of the model, with modifier applied (as you can see there are only quads here):

I export it as obj, the only box I have checked is &quot;apply modifiers&quot;.
In the exported obj you will find a couple of faces which have 6 vertices, which shouldn't happen. Why does it and how do I fix it? It's important that this mesh gets exported as an obj with only quads/bilinear patches
I don't have any way of looking at an .obj file to see where your problem appears, but you have two spurious vertices on the edges of the bottom face which you can see in Blender if you turn off the bevel modifier. Not sure whether deleting those would sort your problem?
