[quote user="Nick Carter"]The properties/attributes of each item we are interested in are ProStructures specific and can be accessed from the ProStructures .Net API[/quote]
If you write a C# AddIn for MicroStation V8i then you are stuck with the VBA (COM) InterOp. That may or may not provide the level of element detail that you want.
If you write a C++ native app.l for MicroStation V8i then you have the most detailed access to elements. You then need to get at the ProStructures .NET API. One way to achieve that is to write a C++/CLR wrapper around the .NET API so that you can call it from your native C++ code. We describe how to do that in this article.
