Hi Nenad,
[quote user="Nenad Poljcic"]I cat Point3d array to System.Array because it was only way it worked in V8i.[/quote]
Hmm ... I don't believe it, but right now I have no time to test it. There is not any reason for casting and Point3d[] works fine in add-in (where should be no difference in this case). I will try to test it in V8i (an maybe also in CONNECT EDITION) using Automation object later.
With regards,
Jan
