VBA - Get actual "Displayed" Dimension

I'm working on a macro that processes dimensions in a drawing.  I'm trying to retrieve the actual dimension shown on the drawing with the least manipulation.  I know i can use GetSystemValue to get the value of the dim, but its not necessarily what is shown on the drawing.

Example:

Sheet dim is 0.5000

GetSystemValue returns: 0.0127

i can manipulate the value with XXX * 1000# * (1 / 25.4)

But after manipulation the new value is 0.5

I just want to retrieve the "Actual displayed dimension" ...in this example is 0.5000
