ASSEMBLY Manager - Constraint colours - some clues

Hi All,
2020 introduces more nuances for figuring out what is not right…

BLACK - the normal constraint color - everything is good.

BLUE - Item is blanked. Constraints will also be BLUE
RED - constraint is Over Defined and needs to corrected.
MAGENTA - Constraint is over defined BUT object is in correct position. In other words you are getting the result you want but the constraint is still in conflict.

I hope that is some help.
Cheers
Paul
