Since this reply was posted (close to a year), is there anything new concerning the future of VBA and/or its alternative in Inventor?
I too have been concerned about this topic.
I've been looking into running VB.NET forms and dialogs encapsulated in a dll library and launched from an external iLogic Rule.
My current problem with that is that you cannot link an external iLogic Rule to a button unless you use VBA.
*Catch - 22*
You can of course doc the Rule browser and run them with a right mouse menu but that is too clumsy for my engineering crew.
