Proxy element like AutoCAD user-defined entity

[Anonymous]

1. Whether revit has proxy element ( like a AutoCAD proxy entity) class type  ?

2. How to handle the move event in "Family" type?

3. Whether the Family has properties set family element be can not move ?

best regards.

Before doing anything else, you need to realise how different Revit and its API is from AutoCAD and most other CAD systems and APIs:

1. No.
2. I guess you mean family instance, not type?
3. Yes, you can pin and lock Revit elements.

Thank you for a great answer! 

There is still a problem:

whether has a method to hand\catch a on-delete or on-move event from a family instance or image element?

I guess : no.
