I really do not understand why the API Solidwork implemented two interfaces ISldWorks and SldWorks?
Why is SldWorks contains events and ISldWorks not? For example OnIdleNotify.
Why when I create a new project in Visual Studio in the file "Addin_EventHandling.cs" (which is intended for realization of the event) is implemented ISldWorks, instead SldWorks?
