Is there a way to prevent users from adding a datum reference to a gtol without the datum existing?
I am testing Creo 5 for my company before we implement it for all of the designers and engineers and I came across this. In the gtol pictured below(I created for this post), it has a reference to Datums A, B and C. However, only datum A exists, datums B and C do NOT exist. How can I prevent someone from accidentally doing this on a drawing that might go to production? Is there an option in Creo 5 that will only let me reference a Datum if it exists?
