Display edges only on some elements using appearance

[FelixGirard]

Is your feature request related to a problem? Please describe.
Using the edit tools, we are creating 2d shapes that are closed (the geometry is a Loop). We have some 3d elements in the background that makes it so we can't use wireframe render mode.

I couldn't find any way to override the appearance to only show the edge of these shapes.
I can kind of make them transparent fill, but that's about it.

Describe the solution you'd like
Would like the ability to say don't fill those shape and use the weight and color to draw the edges.

Additional context
Please don't hesitate to ask for more questions, clarifications or reach out directly. Thanks!

Are they decorations/dynamics, or persistent elements?

[FelixGirard]

Persisted elements

What prevents you from creating a Path instead of a Loop?

[FelixGirard]

I can create a Path (that's what we have right now as a work around). But is has some problems for other tools (like trim / extend). @bbastings

[bbastings]

@FelixGirard What problems? For most tools I allowed physically closed paths to be treated the same as loops...trim should treat them exactly the same.

I think the Trim/Extend Tool works well with what we currently have. The Break Curve tool might have issues with what we are currently doing (Brien and I have talked about workarounds but I've been working on other issues recently and haven't gotten around to figuring that out yet).
