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