Hi! There are two things to check. First, go to Tools -> Application Options -> Assembly -> "In-Place Features" are the two check boxes under "Cross part geometry projection" checked? Second, it depends on where the sketch is at. Is it an assembly sketch? If yes, adaptive is not available in assembly sketch. If it is shared part level sketch, it is currently not adaptable because it can cause interruption to feature compute order.
Many thanks!
