Phil, currently I don’t use UDTs for my AOIs. One, how much more efficient are we talking comparing UDTs to internal AOI data types? I haven’t seen anything abnormal from past projects and have had some high tag counts. Two, what do you do for default values and read/write access if you use UDTs? Having default values has been why I haven’t jumped ship yet. I assume you either don’t use default vales or write code for first pass?
