Ordinate Dimensioning Question

[DREWDIN]

I have placed the x and y datum points on my drawing, Since then I have decided to move the datum points and I cant seem to figure out how. Does anyone know how to move them after theve have already been placed. Thanks

Have u already placed any dimensions off the origin? if so, u'll have to do it again (not parametric) if not just delete them and start again...easy pesy!
