Hi @Rh-3d-p,

Is this helpful?

import Rhino
import scriptcontext as sc

def test_hatch_boundary():
    go = Rhino.Input.Custom.GetObject()
    go.SetCommandPrompt("Select hatches")
    go.GeometryFilter = Rhino.DocObjects.ObjectType.Hatch
    go.GroupSelect = True
    go.SubObjectSelect = False
    go.GetMultiple(1, 0)
    if go.CommandResult() != Rhino.Commands.Result.Success: return
    
    for objref in go.Objects():
        hatch = objref.Hatch()
        if hatch:
            curves = hatch.Get3dCurves(True)
            for curve in curves:
                sc.doc.Objects.AddCurve(curve)
    sc.doc.Views.Redraw()
    
if __name__ == "__main__":
    test_hatch_boundary()
