Brian - I made it work by dimensioning the x/y coordinates of the center mark BEFORE foreshortening the radius dimension..
Dimension the radius to the actual center point. RMB the dimension & under Display Options select Foreshortened. Move the Center Mark where you want it and then dimension your x/y coordinates to the newly located Center Mark. The dimensions of the foreshortened Center Mark will be correct as if it was never moved. To verify, you can unselect Foreshortened and the Center Mark returns to it's original position maintaining the same dimension.
Bob Herfindahl, it should work whether you dimension before or after foreshortening. If you toggle Foreshortened on & off, the Center Mark will move from it's actual location to the location you moved it to when foreshortening it, and the dimensions will remain the same.
Is there a way to do this using Ordinate Dimensions that are dimensioned to the center point?
Alex Lichon, I don't believe you can foreshorten an Ordinate Dimension. Foreshortening is typically for radial and not linear dimensions. If your situation allows, maybe you could Break the object to get the dimensions to fit. Check out this explanation. Foreshortening Dimensions (Radial, not linear)
