I am creating a lip and groove on two parts in an assembly which have a hinge relationship.  Everything works fine when the two are in the closed position but one of the parts fails in any open position.  I know the reason this happens is that the normal direction is the same for both the lip and the groove and that is ONLY true at the closed condition.  Is there any way to define the normal for the lip from that component and the normat for the groove from the other component? Right now one direction is chosen at creation and there is not an option, that I have found, which allows the two different normal definitions, each related to the body which has the feature.
