Hi, Pixero. I have a same problem with continous orbit. I read many post some other sketchup forums about this and just found your post now. You made this script? Can you send the fully working script? thank you and sorry for my english (i have problem with the grammar)
Checkout 3DVIA for the iPad - it allows you to upload a DAE export to their site and view it on iPad with rotate and zoom
