If when I am on a STAR and the assigned transition lets say is, COLTS ( Oakland County Mi. Axxis.Oklnd1) if the controller tells me to proceed direct to another fix on the transition lets say PICUP, does this void the STAR and now becomes a vectored arrival or do I still have to adhere to the published route/altitude step downs??
Simply put, if ATC explicitly gives you any speed restriction, it cancels all speed restrictions on the STAR until ATC tells you once again to resume the arrival (assuming the STAR is non-RNAV) or "descend via" (if the STAR is RNAV).
Same applies for vectoring. If ATC gives you a vector or tells you "proceed/cleared direct XXXXX", that cancels the STAR, including the speed restrictions published on the STAR. To that effect, you've been taken off of the STAR, so you no longer have to adhere to it, but instead have to adhere to ATC instructions.
