Meshing for *.obj File

 From:  Chris
Hi Michael, Hi all,

when exporting to an *.obj file I find the following situation:

Angle 9.43: O.K.

Angle 9.69: ???

Angle 9.94: O.K.

For other target mesh density ranges it's sometimes a little bit tricky to find a working adjustment. I'm wondering if this is a known issue (like mentioned in and if there are any recommendations to work around this.
