How can I mirror an object in SketchUp?

i am having problem regarding mirroring the component like we do into autocad can we do the same in sketchup also?

Right click on the component and choose Flip Along and the appropriate axis.

Or if you want to mirror about a picked plane or line, install TIG’s Mirror tool from SketchUcation Plugin Store
http://sketchucation.com/pluginstore - search the store for ‘mirror’ to find it.

You have to register (free) to download plugins. There’s also a paid for subscription, but while you have to register, you don’t have to pay, to download plugins.

There is also the simple, Copy, Scale -1, Paste in place, option.
