Change datum of ordinate dimension

[nannerdw]

Is there a way to change the datum of an existing ordinate dimension?

I'm using AutoCAD Mechanical 2009.

If the ordinate dimensions are created by AMAUTODIM, you can use AMPOWEREDIT command to re-arrange them.

Thanks, but AMAUTODIM is far too cumbersome for what I'm trying to do.  Each of my ordinate dimensions is connected to the base point of a block reference.  Going through the AMAUTODIM options to pick a single object nested inside each individual block reference is extremely tedious, compared to just picking each point manually.

I figured out how to do it.  When you select an ordinate dimension, it highlights the point at its origin, which can be moved.

Use UCS command and change UCS location at your own starting point .
