Slow orbit and movement after uploading several external models to google earth

[Tariq Hamdan]

I have a problem after loading external models to google earth.

I have a project of several buildings and other objects located in a small area. I did the modeling in sketchup and separated the project to several files; where each file contained a single model (component) repeated several times to minimize the KMZ size. I had 10 files in the end.

I uploaded the files to google earth as external models and it uploaded in a relatively good speed (no complains here). But when I try to orbit and pan using the mouse between the models while all the models are visible in the screen area I get a slow movement.

When I zoom in near the models the movement improves and becomes smooth.

Although in google earth itself there are too many models in a small area like New York city, you don’t notice any slowness in the movement.

Can anyone help me and tell me why is this happening? I need to fix this problem and make the movement smooth regardless of the number of external models I upload.
