Problem exporting .mb file on .obj

[Anonymous]

Hello,
I'm a beginner.

While exporting an .mb finished file in .obj, one part of it transforms like if some segments that construct its part on the right is crashing between the two pieces that constructs it. It seems to be about booleaning, it is the only booleaned part but the crash seem to be only in one side.

I tried to cancel some booleaning and it seemed to be ok, but when i zoom in .obj I saw other little craches that i join in picture : 

On the .mb file everything seemed to be good 

Thank you for helping me

Please upload more snapshot of your problem.

Try to Delete History of your scene and then export to obj or else you can save your mb file in ma and then try to export obj.
