Alternate dims based on formula?

[Anonymous]

hi, i'm new to posting but have used this forum countless times with previous issues so hope you all can help.

is it possible (Revit 2014) to set up alternate dimensions that report the value represented in a different way via a simple formula? 

I am trying to show my dims as brick units (based on standard metric bricks 215x102.5x65mm with 10mm mortar joint), and was hoping to create new 3 dim types, based on CO+, CO- and CO, so the alternate dims i want would be:

1. CO+ =[value-10]/225
2. CO- =[value+10]/225
3. CO simply =[value/225]

....with the appropriate suffixes (CO+, CO- and CO).  Anyone know if this is possible..... or on the cards?

I don't think such an option is available, at least not without some custom programming (maybe). What is possible is a dimension type that provides different ways of showing a series of equal-equal segments, as in this exampe. But you would have to draw all the reference planes.
