Tangent edges linetype in Drafting Layout

Is it possible to change tangent edges in Drafting Layout to different linetype syle?
For example DashDot linetype with grey color.

Did you use Make2D to get the curves?

Non, I use Rhino solid or curve modeling than I add new layout and details.

The display modes do not have settings that would let you do this on (poly-)surfaces.
Your only option is to use Make2D and modify the layer properties for the tangent layers.
