We are in the process of recording a DevTV on "AutoCAD Map 3D 2013 - new Features and API" which we are going to upload this week. We are not hosting a separate "Live Q & A" session on Map 3D API; you can use the comment section here to ask your question on Map 3D 2013 API, alternatively you can use Map 3D Developer discussion Forum to post your question. Those who have access to Partner Center, please use the same to ask your question and we will respond to that.
