Why does Brep.Split completely fail if just one curve in a collection fails to split the brep?
import rhinoscriptsyntax as rs
import scriptcontext as sc
import Rhino, System
from System.Collections.Generic import IEnumerable
def SplitBrepWCrvs(brepID,crvIDs,tol,del_orig=True):
brep=rs.coercebrep(brepID)
crvs=[rs.coercecurve(crvID) for crvID in crvIDs]
splits=brep.Split.Overloads[IEnumerable[Rhino.Geometry.Curve],System.Double](crvs, tol)
if splits:
if del_orig:
rs.DeleteObject(brepID)
return [sc.doc.Objects.AddBrep(brep) for brep in splits]
brepID=rs.GetObject("Select surface",8)
crvIDs=rs.GetObjects("Select curves",4)
tol=sc.doc.ModelAbsoluteTolerance
parts=SplitBrepWCrvs(brepID,crvIDs,tol)
if not parts: print "Failed!"
else: print "Surface split into {} parts".format(len(parts))
Select all the curves in the file below, it fails. Select only the black ones that go through the surface, it succeeds.
