Mirror about a point

Is there a simple method to mirror an object about a point?

The current method I use is:

ScaleNU
Origin point: select or enter point to mirror about
X axis scale: enter -1
Y axis scale: enter -1
Z axis scale: enter -1

I suppose I could create a macro for this.

I know of several other methods including three successive mirrors, and a mirror and rotation. However both of those methods are more prone to error.

Hi David - I think a macro would be best - Gumball also works, if the location suits you: - Shift click in a scale handle and type in -1 and Enter.

-Pascal

Scale command with a negative scale factor would also be useful. It is not obvious why negative scale factor works with Gumball but not the Scale command.
