How long should a large model take to start rendering?

I can render a smaller model – when I render a larger model after a short time sketchup will not respond! All my work is large exhibition stands, is this going to be a problem?

Some large files do take a long time to save the data. Some times someone sends me a large file that I think is too large to render, but if I let it go over lunch, for example, I come back and it has started
rendering.

Models with a lot of components can be very large for rendering even if they are not that big on the hard drive.

If you'd like, you could send us one of your models and I could render it here to make sure it
works, and give you an idea of how log it took to save the data.
