The character of Ebenezer Scrooge is visited by the ghosts of Christmas Past, Present, and Future in Charles Dickens' classic story of A Christmas Carol. You can visit the catalog page to download Plugins of the Month Past, Present, and Future. This classic page has all of the plugins from August 2009 when Kean Walmsley started this idea, and our plan is to post all plugins there until the Autodesk Developer Network (ADN) Plugin of the Month program graduates from Autodesk Labs.
The catalog has free plugins for AutoCAD, Inventor, Revit, and 3ds Max. The ADN plugins include the source code to encourage customization for additional or user-specific functionality.
Visitation is alive in the lab.
