Here is a succinct overview of some resources available for getting started using the Revit API, compiled by Mikako Harada. The individual items have been mentioned in previous posts, and links to those are included. This document provides a useful and up-to-date overview for the current state, still focused on Revit 2009. You can expect an update of this material later in a couple of month's time, when the training material has been enhanced for Revit 2010.
Revit Product – you can download the latest version of the released products from the Autodesk product page > Products > Alphabetically. From each Revit product page, look under Product Download. Here are the current links, but note that the exact locations may change:
Without an activation code, you can only use Revit in view-only mode.
Revit SDK – the Revit SDK is included in every Revit install.
RevitAPI.dll is part of every Revit installation and is located in the folder
Development Environment – Microsoft Visual Studio 2005 for Revit 2009, and Visual Studio 2008 + SP1 for Revit 2010. The Express edition can also be used.
Revit API Documentation – The Revit SDK includes a Developer Guide, help file, and many samples. More detailed information on the SDK contents and how to manage, build and load the samples was discussed in some early blog posts:
Yet more information for beginners is included in the Getting Started category.
a. Watch the training video - The best way to start will be to watch our webcast material. This includes a recording of the webcast, the Powerpoint presentation, and training labs source code. This material is also available from the Developer Center training schedule page. There is a Revit Architecture and Revit Structure section in the Developer Center which provides other material including a polished version of the recording called DevTV, which is available for download or online viewing. It is slightly out of date, being based on Revit 2008. But you can still get the basic idea. You may want to see which one is suited for you.
b. Try running the HelloRevit sample yourself, go through the Labs code, and then look at some further samples in the SDK. The following samples provide good starting points:
c. A must-have tool is RvtMgdDbg, which we discussed in a separate post.
We will be migrating and updating our training material for the Revit 2010 API in the coming months. The first intermediate result will be the webcast training on April 29th. If you are interested in learning more about what is coming for Revit 2010, please take a look at the recording of the recent Developer Days Online AEC webcast.
