Change line weight or color in a drawing

Hi everyone

Is it possible to change the color or thickness of a part line in a Solidworks 2014 drawing, and if so, how? 

Thank you in advance;) 

It's okay I found I hadn't seen the icons at the top that are displayed when I right-click on my line.

Hello

To do this, it is necessary to use layers: http://help.solidworks.com/SearchEx.aspx?q=CALQUE&sort=&version=2016&lang=French&prod=SolidWorks&context=LANG%3den%26NRESULTS%3d25&refine=f%2farea%2fhabillage+et+mises+en+plan
