Creo now automatically chooses the reference plane for you when you select a sketch plane directly at feature creation or from the main dashboard. This is a time saver, but frequently causes sketches to be oriented differently than the user desires and can cause unwanted parent child relationships.
While a user can use a specific workflow (selecting define from the dashboard), having a config option that would present the sketch setup dialog to the user every time would help users who desire to control the reference plane to do so.
Create a config option (auto_choose_ref_plane?) to force Creo to allow the user to choose the reference plane regardless of how the user enters the sketch environment.
