David,

Sorry about the poor wording of my question. Despite that I believe
you have found the solution to my problem! It looks like the PickData
method will indeed do the job.
I'm still more of a direct graphics guy but with the help of your
book, Ron's book and Rick's camera object I'm trying to change all
that.

Many thanks,
Bill
