Dave R,
Sadly the link you sent are for Sketchup Pro users, I am using the free version Sketchup Make 2016. With the obj plugin for Make 2016 it does not give us the "OBJ Export Options" like the pro version gives you. It just gives the option to save with converted textures into PNG files or not.
I tried reversing the faces so they are the correct way, and it does nothing to the exported OBJ file. Still adds why too many edges.
Any other ideas?
