How to scale lines in layout?

How does one scale lines , e.g. dashed in rhino? In AC there is a scale factor in properties. I can’t find any such option in Rhino.

there is a linetypes scale setting in File>Properties (setlinetypescale), there is also an override in the print dialog to match viewport or world.

Thanks for this info.
Am I understanding this correctly that these options affect all similar objects? In AutoCAD, linetype scale is an individual object property.

Correct. To customize to a particular object you would need to create a new linetype to suit.
