SolidWorks Mechanical Part Modeling & Analysis

I need a complete SolidWorks model of a mechanical part, built from the ground up with every component accurately represented. The file must be organised in a way that lets me edit dimensions and configurations later, so please keep the feature tree clean and fully parametrised...
