variation opacity

Hi! On solidworks ,In a development plan, when my assembly is finish, can I change the variation of opacity on different type of line when we detailling ? Like the dashed line is more paler and the first step of my assembly is more darker exemple? I would like to gamble with different type of line like autocad? layers or ? how I do that?

thanks

and also if I would like to change the opacity of one objet in my assembly where I go to made that?

exemple: A grill on a plate, I would like to have my line of my plate more darker and the grill more paler, for the detailling
