Closed curve to layout

Hi!
I would like to porpose a new order. In autocad it exist…
I would like to convert a closed to layout. At this moment, rhino only can made a rectangle.

I am reading this as a wish for having the option to make non-rectangular details on a layout - like when you need to enlarge a detail of a bigger drawing.
This is on the wish-list as item RH-2574.

The current workaround is to have a solid white hatch with custom internal border (a hole in a rectangle).
