How to fix this problem?
 

I am importing structured cgns file with Hex cells. When i am importing it and after that checking grid it gives me following message . checking face handedness.

Zone 2: 25186 right-handed, 14 left-handed

Zone 5: 444128 right-handed, 208 left-handed

,but when i am reparing it with text command grid/modify-zones/repair-face-handedness then it repairs that thing but at the cost of converting grids min volume into non positive volume. so can anybody pls help me? Thanks regrads mehul
