The DevTech team spends a substantial amount of time delivering API training, and not just to ADN members. We schedule class-room trainings at various Autodesk facilities, deliver training on-site at developers' offices, and deliver training webcasts via Microsoft LiveMeeting.
Mikako Harada, the team lead for DevTech East Asia and the technical lead for our BSD workgroup, will deliver a webcast on Architectural Desktop's .NET API on July 13th. This webcast is absolutely free to everyone.
For more information on our API training - and to register for the webcast - please check Autodesk's API training page at http://www.autodesk.com/apitraining. For your convenience, here's a direct link to the API training schedule.
By the way - we do post recordings of our API webcasts to the ADN website, although you do need to be a member of ADN to access them.
