Outer contour curve from mesh

Hey guys,

I imported a mesh into grasshopper based on a .stl file.
Now, I would like to capture the outer contour of the mesh by a curve.

Do you have any idea how to do this?

Thank you in advance,

Dominique

If you’re referring to getting the naked mesh edges as polylines, there are some examples of this here: Get Internal Naked/Open Mesh Edges

Unfortunately, this is not what i was looking for.

In Rhino there is a option calles “Mesh Outline” (Curve - Curve from Objects - Mesh Outline) that gives me exactly the contour of the mesh.
As of yet, i could not figure out if there is a similar module in grasshopper.

It could be make2d component that you need or contour ?

No, i just need the contour of the mesh.
Attatched you can find an image of the mesh.


By choosing the mesh and using “MeshOutline” i receive this:

In order to be more flexible, my plan is to do the entire work in grasshopper. Therefore I am looking for the right module or module combination to receive this outline curve.

Dear Laurent,

this is exactly what i was looking for!
Big Thanks to you!

Best,

It does though, MeshOutline appears to get the naked perimeter and project this to (some) plane:
