Good news. 🙂 Autodesk Plant Support has started a new Plant 3D Video Blog Series which are now available on YouTube.
See this link to get more information about this series.
And here is the playlist of this series. Currently there are two uploaded videos: one which explains a bit the purpose of this video blog series and the other one is a general introduction for AutoCAD Plant 3D.
This playlist will be updated on a monthly base.
