How To Best Walk Around Houses Created in Revit Or Sketchup

 I have imported a house .kmz file from Sketchup into Google Earth and sometimes I am able to get my camera perfectly inside the house but the native camera controls are very jerky also I have no vertical adjustment for changing floors. Does anyone know of a better way to control the camera as if you were walking? Also, does anyone know if its possible to get .kmz files into the earth environment while using a htc vive? I'm basically looking for better ways to interact with my models in google earth. Any help is appreciated. Thank you!

It's probably not what you're asking, but I've found that the most satisfactory way to navigate around models is to put a series of views in a folder, and then record a tour (something like THIS).
