'Use C# for Catia V5 Automation

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.)

Solution 1:[1]

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.

You can do this:

  1. Add the INFITF typelib library in reference, which is an interface to the CATIA application
  2. INFITF.Application CATIA;
  3. Create Button inside; e.g., 
    Private void buttonX(object sender, EventArgs e){
    CATIA.Visible = true;
}

  1. Adding reference to CSProj:

As suggested by Selin Raja M; you have to "Add INFITF typelib library in references which is the interface to CATIA application (CATIA V5 InfInterfaces Object Library)". Simply follow: Project --> References --> Add ---> COM --> CATIA V5 InfInterfaces Object Library

  1. Binding the CATIA Application and Using inside CSProj

     using INFITF; 
 namespace SampleCatiaProj
 {
    public class LoadDocumentClass
    {
          public static INFITF.Application CATIA;
          public bool LoadDoc()
          {     CATIA = 
             INFITF.Application)Marshal.GetActiveObject("CATIA.Application");
             CATIA.Visible = true;
             CATIA.DisplayFileAlerts = true;

             ProductStructureTypeLib.ProductDocument oRootProductDocument;
             oRootProductDocument = (ProductStructureTypeLib.ProductDocument)CATIA.ActiveDocument;

             // Some code goes here

             // Keep on adding code as per CATIA V5 automation API

             return true;
       }
    }
 }
