I downloaded a couple of helicopters from Google Warehouse.

I thought I could do this in 3D Exchange, but I can't figure it out.

I want to have the propeller blades and tail blades rotate. My idea is
to create a little animation of a helicopter tour of the Las Vegas strip
using a Google Earth movie of the strip as a background.

I don't see why the helicopter blade rotation can't be done in a 3D animation,
but I'm drawing a blank. I though I would have to group the blades and the
part the blades are connected to and then just rotate on axis? But I guess 3D Exchange
doesn't have a group option.

The other thing is when I export from 3D Exchange to iclone, the helicopter is one
whole object. I cannot pick just the propeller blades?

Ideas?

Thanks,

Ray
