Hello all, I'm trying to find a way to export "extended data" for use in Google Earth. Using blocks seems to work because I can define attributes, and that seems to migrate well.
I haven't found a way to do the same with the linework in my DWG files. I've looked pretty extensively and came up empty. There might be functionality using C3D that I'm not aware of that will do this. I know it can be done, I've seen some KMLs that have the additional data. Maybe they were using some code that does this.

I'll attach a screen grab of an example of the data I see while hovering over a route in GE, keep in mind its not exactly the data I would like to attach. It's just an example to show that it can be done.

Thanks in advance
