How would you create surface breaklines in SU?

[SailingSketcher]

I’m curious if anyone has created a workflow to generate breaklines in SU? If you haven’t but you think you have an idea for how you would go about it if you needed to, I welcome the input.

Breaklines like this?

This is done in LayOut with no need to actually break the component.

Or do you really need to show the object broken in SketchUp? When I’ve needed to do that I’ve created a volume with the break shape and used it to trim the object being broken.
