Michael Gibson,
Many thanks about idea with CPLane! I just examine my projects, the thing was that I have set Template file with shifted CPlane... It drived me crazy to uderstand what is wrong, becouse I reset all settings and reinstal MoI but problem was still here, many thanks again it was Template File... :)

No problem Andrei - yes if you have a custom cplane set (which if it's in the startup template file means you will get it in your default opening setup), that will control the visual placement of the grid in MoI but not have any effect on .obj export.

Sounds like you are all set up now.

- Michael

Yes, thanks!
