Global Parameters - Contraint Warnings

I am setting various pier edge distances up throughout the foundation. There are about 8 different piers and each has a specific edge distance from the internal wall face. I am trying to use global parameters to drive these edge dimensions and have the ability to update the edge distances parametrically. I can set the dimensions and drive them individually using the global parameters, however, when trying to change more than one dimension at a time (often the piers have an "A" and "B" edge distance), I get a constraint error:

Is this something I cannot do in Revit?

I'd guess that the family "grows" in a way that is incompatible with changing both parameters at the same time. For example, when you change the parameters in the family itself does it flex outward from the center/origin or from one side?

The Structural Column Family is not changing. It is moving location though based off the global parameter.

When you apply a dimension are you noticing what the tooltip/status bar reports for what Revit "sees"? Depending on how the family is created it can dimension to a reference plane or the edge of the form...the tool tip should change when you use the TAB key to cycle through possible references for the dimension to attach to. Does the Global Parameter behave any differently when you dimension to different parts of the family?

Can you post a small mock up project of what you're doing?

What Constraints are affected? Maybe it's nothing more than a dimension you placed. Maybe pulled from the wrong elements or maybe locked.  What's it say under Expand>>?

It looks like when I updated the global dimensions, it is trying to keep the piers where they are and move the walls. I want the piers to chance because this is an edge distance from the walls. How does Revit know what element to move?

Typically, when you dimension between two elements, it is the element you picked first that moves when the dimension's label value is changed.
