Sketchup hangs indefinitely

Hi all

I am a newbie. I am trying to render with default settings, and sketchup seems to hang for hours on end. Am I doing something wrong?

Re: Sketchup hangs indefinitely

On large models with large number of materials, it takes longer for VfSU to prepare for the rendering process. This process called parsing.
There are ways to decrease the parsing time:
1. Purging
2. To apply materials directly on faces, i.e not directly on Component/Group. There’s a great plugin that ‘fixes’ those C-G: Remove C-G Materials

Re: Sketchup hangs indefinitely

what is mean “1. Purging” ? :d

Re: Sketchup hangs indefinitely

Every time you use a texture or component, this data is stored in the SketchUp file. Based on this information, you can purge the SketchUp file, which also helps reduce file size:
Click Window > Model Info. The Model Info dialog box will open.
Click Statistics > Purge Unused.

Thank you so much for all your responses! I am a newbie, and I am still learning.
The CG plugin really helped me from going insane:)
