I want to write Macros/Programs for Catia V5 with the programming language C#.

How is it possible to access the Catia applicataion via c#(and Visual Studio). I searched a bit and found out that Catia provides an API, which the Microsoft COM Technologie provides for 'COM-languages' like c# & python.

This is how I imagine the connection/interaction between a C# Programm and Catia:

C# - .NET <-bi-directional integration-> COM <-> Catia API

Is that correct ?

Also: How do I setup everything in Visual Studio , so that I can access the Catia API (and code completion etc.)

1) Add INFITF typelib library in reference which is interface to CATIA application

2) Define CATIA as global variable as like 

   INFITF.Application CATIA;

3) Bind the catia application to your CATIA variable as below statement

   CATIA = (INFITF.Application)Marshal.GetActiveObject("Catia.Application");

Hope this would helps you to get started.
