Importing Sketchup to Google Earth

New to SU and trying to upload a residential home to Google Earth, I get an error of too many vortices - more than 64k. Is there a way to reduce the file size?

Possibly. Without seeing the model it’s hard to say exactly. Might be as simple as purging unused stuff from the model. Maybe you are exporting a bunch of stuff that won’t be seen anyway. If so, make a copy of the model and gut the interior so you’re only left with the shell. Remove any details that won’t be visible. Purge unused to make sure it’s not included.
