An Application Program Interface (API) is like a handshake.
The Google Earth Extension for AutoCAD is our technology preview that allows you to publish your 3D models from AutoCAD-based products directly into the Google Earth application, import a Google Earth image into AutoCAD, drape a Google Earth image onto a 3D mesh in AutoCAD, and attach time span information to your model.

The extension is a little bit of code that acts as glue to connect Google Earth to AutoCAD. It does this through available APIs. The original Google Earth only supported a Microsoft Common Object Module (COM) API. Our Google Earth Extension made use of this API.
Then on August 31, 2010, we read this on the Google Geo Developers Blog.
Sunset for the Google Earth COM API
Based on this information, I updated the Labs site to indicate that Google Earth 6 was not supported; however, as it turns out, with the release of Google Earth 6, support for the COM API remains but has been augmented with a browser plug-in and a JavaScript API known as the Earth API.
The team is considering updating the extension to "shake hands with Google Earth" using this new API. If this happens, we will post an updated technology preview. For now, the COM API continues to work. I have removed the Google 6 disclaimer from the Labs site.
Please continue to provide your feedback at [email protected]. So far, we've gotten some great feedback.
Sharing the nuts and bolts is alive in the lab.
