only a small portion of your processor is being utilized, due to the single threaded nature of Ruby. We have identified the cause for the slow export process, and it is fixed in a nightly build. If anyone is interested in testing a nightly build to see if it works better for them, please contact me.

Hi, how can I contact You ? Cause i have the same issue - sketchup freezes and nothing happens. Small object are ok, and I can export them to proxy without any problems, but objects with larger geometry always cause problems. I just can't export them.
Has anyone else solved the issue ?
