My current method of sending a design to Google Earth is to first save the project as a .kmz file and then open it up in Google Earth. Nine times out of 10 this usually works without issue. I know it is possible to send the design while still in AC but my designs are big and can tie up AC for quite a while. The issue I have with that one time it doesn't work is that Google Earth pops up a window stating that it will close because it cannot read the "file name.dae" file. Any thoughts on what could be happening? Note that my .kmz files typically run from 50M to 100M.
