Use C# for Catia V5 Automation

Question

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.

Thanks, you are the best ! Whre can I download the INFITF library ? I have foun this instruction called "How to: Add References to Type Libraries" (https://msdn.microsoft.com/en-us/library/fwawt96c(v=vs.110).aspx). And don't know how to do the first step "1.Install the COM DLL or EXE file on your computer, unless a Windows Setup.exe file performs the installation for you." – Blackpanther0001 Nov 23 '16 at 16:12

You can do this:

Add the INFITF typelib library in reference, which is an interface to the CATIA application
INFITF.Application CATIA;

Create Button inside; e.g.,

Private void buttonX(object sender, EventArgs e){
    CATIA.Visible = true;
}

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

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;
       }
    }
 }
