Configuration

I'm a Mechanical engineering major and it is my first time taking
solidworks. Can anyone give me an example how to create a
configuration from existing parts?

Thanks

 

I don't really understand the question.
"Configuration" is a specific term in Solidworks (and most other 3D apps)
which refers to a the ability to have variants of an item all contained
within the same file, rather than needing to create multiple files.

I wonder whether you mean "how do I create an assembly from existing parts"?
If so, then take a look at the Solidworks help files and also do the
tutorials, and then feel free to ask some more questions.
