Some more details of the changes in the updated version for AutoCAD 2008 Google Earth Extension posted to Autodesk Labs May 24th,2007 for both AutoCAD 2007 and AutoCAD 2008. The AutoCAD 2008 version was just updated today to address two issue reported over the weekend.
1) It now supports materials attached to AutoCAD entities. Yes the nice better quality ones of Google Earth 4 via Collada.
2) Imports terrain data as 32x32 grid AutoCAD mesh (with material automatically attached)
3) Support for attaching time to AutoCAD entities for use with Google Earth’s time slider feature. So you could animate project or model changes over time in Google Earth.
4) Numerous resolved issues reported by users of the previous version using the email for the tools feedback of email of firstname.lastname@example.org
I had some geeky fun this weekend testing out the extension with AutoCAD 2008. I modeled a 3D model of the Autodesk offices known as Civic Center buildings located in San Rafael California where much of the AutoCAD Team is located/caged :-).
I then exported the model of the two buildings into a KML file for viewing in Google Earth using the command "PUBLISHKML" and to the properly place using the coordinates of the image I used as a base reference with IMPORTGEIMAGE .
I posted a series of screen captures during the process to my Flickr image Gallery for AutoCAD.
