In my earlier post today, I pointed out that Google changed the rules and has made it impossible for Civil 3D to build a surface from Google Earth 4.3. I did some digging though, and I found a way to make it happen. Read how and learn the limitations after the jump.
From my digging around, it seems that GE has limited the amount of data that can be accessed to 5000 points. The default in the ImportGESurface and ImportGEData command settings is 100 rows X 100 columns, or 10,000 points. This is why Civil 3D gets stuck around 50%.
To fix this, go into the command settings and change the rows and columns to give you something that will result in 5000 or fewer points. (You know, like the square root of 5000.)
The surface will build. Has the resolution been affected? The only conclusion that I can come to came to me in a dream. You bet it does. Going from 10,000 points to 5,000 points means that our conceptual surface is even more conceptual. While I haven’t been able to find an official proclamation from Google on the subject, I suspect a slice in resolution might be their motivation behind the change. But what do I know.
