My First AutoCAD Plug-in:

Video: Overview of My First AutoCAD Plug-in Guide
"My First Plug-in" is a self-paced tutorial guide for a smooth introduction into the programming world. This is a "one-stop shop" learning path for users who know Autodesk products but are absolutely new to programming and are thinking about taking the plunge. In this guide, you will be working with the AutoCAD .NET Application Programming Interface (API) and the Visual Basic .NET programming language to create a ‘plug-in’ – a module that loads into AutoCAD to extend its functionality. Once you have finished this tutorial, you will understand the basics of .NET programming and how they are applied to AutoCAD.

The AutoCAD developer documentation explains the components that make up the available APIs for AutoCAD and AutoCAD-based products.

      A CHM version of the Managed .NET Developer’s Guide can be downloaded and copied into the Docs
      folder  of the ObjectARX SDK.

      The Managed .NET Reference Guide can also be integrated with Microsoft Visual Studio. 

      Member and parameter descriptions from the Managed .NET Reference Guide can be displayed within the
      Microsoft Visual Studio environment as part of the Intellisense feature set. This allows for some          
      basic  information  about a member or parameter to be displayed in a tooltip while working in a code
      editor window or to be accessed from the Object Browser without the need to open the Help Viewer.
      Download the appropriate file below and extract the XML files into the Inc folder of the ObjectARX SDK.
