Creating frames for a track car in SolidWorks

I am trying to create a frame/rolling chassis for a track car, but can't work out how to turn a 3D sketch into pipes to make the framework. Please Help!

Use Weldments!! They are pretty helpful when making Frames.

as told by Sudhir gill sir u can use Weldments in SolidWorks.
If facing difficulties then u can also use surfacing.

I find the best way to do it is by using profile sweeps, and projected curves. It works really well and you can get really accurate drawings.
