Hi,
Thanks for your input. Unfortunately I have maybe a hundered models that would need restructuring, and this still does not get around my basic problem of having multiple instances of the same model, each possibly with different nodes turned on and off. Looks like I need to individually switch each node on and off at traversal time. I had hoped that a parent’s NodeMask (or something similar) could be ANDed with its childs to produce the result I wanted Again thanks for your suggestions Mark HYPERLINK "mailto:[EMAIL PROTECTED]"[EMAIL PROTECTED] Tel +61 (0)89335 1239 Mob +61 (0)405 095 104 No virus found in this outgoing message.
