I need to split an object using a line and delete the left side. How can I do it automatically using the python script?Example.3dm (65.4 KB)
Moved to Scripting category so it will be seen.
Let me know if this code sample is helpful:
import rhinoscriptsyntax as rs # # Split a curve with a cutting curve # def test_split_curve(): # Select the curve to split curve = rs.GetObject("Select curve to split", rs.filter.curve) if curve is None: return # Select the curve to use as the cutter cutter = rs.GetObject("Select cutting curve", rs.filter.curve) if cutter is None: return # Intersect the curve with the cutter intersection_list = rs.CurveCurveIntersection(curve, cutter) if intersection_list is None: return # Look for point intersections parameters =  for intersection in intersection_list: if intersection == 1: # point parameters.append(intersection) # first curve parameter if len(parameters) == 0: return # To split a closed curve you need at least 2 parameters if rs.IsCurveClosed(curve) and len(parameters) < 2: return # Split the curve rc = rs.SplitCurve(curve, parameters) if rc: rs.DeleteObject(curve) # optional # Check to see if this file is being executed as the "main" python # script instead of being used as a module by some other python script # This allows us to use the module which ever way we want. if __name__ == "__main__": test_split_curve()
Thank you very much!! It’s perfect.
