I make molds and work with negative and positives. Within my work space my colleague scans the molds and product and compare with 3d data.

Often i have a problem that i export a surface with flipped sides of surface then the colleague needs. 

Ai told me there is probably option to put different colors on the sides of surfaces in graphic settings. But  i cannot find me.

Could you help me? 

By the way is AI going to be ever implemented for help in catia? there is so much to set in preferences and so much categories and subcategories i never can find what i need
