I have noticed that when you have EQ constraints on two Reference Planes that also have an Overall Dimension Parameter, i.e. Width for a family with a centered Origin (figure 1.jpg), you will get the always annoying "Constraints are not satisfied". (figure 2.jpg).

My tip is to trick Revit a little.  In the screenshots i have dimensioned from object to anchor, so from Inside Offset RP to Left RP.  This should work, its been done before, normally by dimensioning Width last.  But if this is not possible as you're too far down the track then try this...

Pin the Left RP then add the Offset Dimension (figure 3).  Then un-Pin the RP and try and flex the family.  Works!! 

The only thing that you have to keep in mind is that you are dimensioning correctly (what I call object to anchor) 

Good Luck
