This channel features videos related to working with CAD and ArcGIS by Don Kuehne, Esri's CAD Product Manager. It features some topical videos regarding the use of the free ArcGIS for AutoCAD plug-in from Esri. The movies include ways to integrate Bentley Microstation products and the AutoCAD family of products from Autodesk with Esri's ArcGIS system.
