Last time I checked, I could view, but not change, an already-placed family that used a lookup function in RAC.
Workaround -- The same functionality (I think) can be done with a conditional statement. E.g:
Code:
Tap Thickness = if(Tap Diameter < 0' 1 1/4", 0' 1 1/16", if(Tap Diameter < 0' 2", 0' 1 5/16", if(Tap Diameter < 0' 2 1/2", 0' 1 5/8", if(Tap Diameter < 0' 3", 0' 1 5/8", if(Tap Diameter < 0' 3 1/2", 0' 1 3/4", if(Tap Diameter < 0' 5", 0' 2 1/4", 0' 3 11/16"))))))
