Hi Gani,

With the rotate tool (rotating a single "hole" around the center of that disk), you can make copies (so called "radial arrays") if you press the Ctrl key (same with the move tool - called "linear array").

Here is the help center article: http://support.google.com/sketchup/bin/answer.py?hl=en&answer=94896

Now if you make the first hole into a component that can also cut a hole automatically, all the copies on that same plane will behave the same way.

Hi Gaieus:

Thanks for your tip. It was very useful and I was able to do what I wanted.

Hi all:

I am awed by what SU can achieve and feel totally humbled as a newbie. I have a simple question. How do I go about modelling a disk with slots equally spaced around the disk? I think it is easy to visualize, but I'm attaching a file anyway.

thanks,
Gani -
