Wyliepoon, thank you for all of your models. They're brilliant. I have played with Google Earth ages ago so I'm not too familiar with adding models to the program now.
Tonight I was able to download the Casa model and can fly around it, which is cool, but I can't seem to add more than one building to the map. (I have a feeling my graphics card or MAC OS just isn't advanced enough. (It looks like you created the CASA model and the 1 Bloor model with different Sketchup programs... I wonder if that is causing the problem?)
Also, a minor point about your Casa model... the outdoor pool etc will be on the west side of the building, not on the east.
