thanks for the info guys. ill keep tinkering. im pretty sure i tried PPG.Inspected[0] (as its a collection of potentially multiedited ppg's) without any luck. i think the main problem is the lack of error messages, im probably one very small typo away from getting this correct.
grid data sounds like an interesting approach. i could even present the grid data in an "expert" panel of the ppg? that would expose some nice tweak options after the initial generation. ill keep fighting and see what happens thanks _sam
