Topic Title

I've noticed that when using an x-ref in Data Cad there seems to be very little or no control when trying to snap accurate dimensions to an x-ref. Is this inherent to the program? Also interested in why some drafting preferences (particularly tolerances, rounding, etc) follow the drawing rather than being a "user drafting setting".....This is huge if you don't want dinmensioning issues to crop up later in the project.
