Parallel grid lines, not Parallel.

Parallel grid lines, not Parallel.  

Two dimension strings on same grids.

Each dimension string shows different dimensions.

How can the same parallel grid lines be even at the South end, but uneven at the North end? 

Any solutions would be appreciated.

Did you draw the grid lines or did you create them by pick lines from a CAD file?

Yes, big mistake to snap or align to any DWG lines.  Nevertheless, after correcting grids, it is perplexing that dimension strings snapped to grid lines, show different measurements depending on their location, along the grid lines. Usually when lines or elements are not parallel, dimensions will not stick or are not allowed – unless you are snapping to a point. In the attached example, dimensions are snapping to lines, not points.

When the degree to which they are not parallel is tiny they relaxed the intolerance for placing dimensions. I'd rather see this situation than not see it and not know they are at a fussy angle needlessly.

 

Sketch a reference plane horizontally, snapping to just one end (the best end) and sketching past the other end. Use the Align tool to fix the grid so it is aligned to the horizontal reference plane. Delete the reference plane afterward.

Revit refuse to place aligned dimensions when the lines are not parallel to a certain degree.  When the angle is smaller than that it starts to accept the dimensions.  Some can change the dimension format to round up but I personally encourage drawing them properly, especially for things like levels and grids.  The reason is when you mirroring elements multiple times using those grids the problem can amplify greatly.
