Offset mesh borders

Hi everyone, I’m trying to offset outwards the borders of a mesh, kind of a group inset but for the outside direction. What would be the best approach?

Tryed to pipe the naked edges to get the outside lines however some corners don’t work as expected.

Any advice is very welcome.

Check Offset Mesh component from Pufferfish. I think it does what you want

Thanks Alfredo, this definition will be running on a Rhinocompute based platform that does not support plugins, will need to do it the hard way

Maybe this way ? ( Tried to make a mesh similar to yours to show)

Thanks Ali, but I’m not looking not looking to thicken the mesh. The idea is to outset the boundaries

Would you attach your file ?

Sure Ali, note this one is attempting to inset the mesh

Here’s another attempt but also got issues on the same corners

Maybe you can try to consider the Pipe/Mesh intersection.

But the mesh needs to be converted to polysurface.

Just tried this but got the same issue as before, since there are 3 points on the critical corners it will grab the closest one making those edges not aligned with the geometry

Split Brep?

This is a great approach, exactly what I was after, thanks a lot Riccardo
