Get the Autodesk Revit SDK from ADN or the installation DVD. The Autodesk Revit 2011 SDK can be unpacked and installed from the Tools and Utilities option in the installation DVD. In the SDK, there are example files that will help you get a better understanding of the API and its use. Each example file has a sample revit.ini file with the information that you will need to edit and place into the revit.ini file located in your Autodesk Revit Program folder, which Autodesk Revit will access on launch.
• Unzip the SDK onto a local drive
• Read the Read Me First.doc in the SDK
RevitAPI.chm is the Autodesk Revit API reference documentation help file, included with the SDK package in the \Revit 2011 SDK\ folder.
