Is it possible to create a user-defined type which can have parent-child structure?
Hi, I'm wondering if it is possible to define a new subtype of WTDocument which can have both WTPart and WTDocument as its child? Something like a parent WTDocument Order A, and it has child Order A-1, Order A-2, which both contain a series of WTParts.
I'm using Windchill 12.1
Thank you!
