You got.

Thanks. 
By the way, why complanar quads are such a bad thing?

There's no conditional edge line across a coplanar quad surface. And this make the part look like it is missing edge lines

It's when they're not co-planar that it's bad. Or rather when their vertices are not co-planar. Or rather, when either of the two triangle pairs into which the quad can be split are not co-planar…

But yeah, it's because it causes parts to be rendered with a surface that appears to be curved but isn't. Or vice versa. (And probably more fundamentally, because it's topologically invalid in a 3D model.)

Fixed mentioned problems

Would like to know if there's anything else to be done before part can get a pass
