Hi everyone, I have tried to use the MEPover node Pipe.byLines. I am working in Revit 2024 and the Python Code of the script is still in IronPython2. Obviousely I have updated the Code to CPython3 via the integrated code update in Dynamo, however, the node is not working. I have used the script before in Revit 2023 and it was working fine. However now Dynamo starts loading and just never stops loading every single time i try to run it. I first thought it was the list that is at fault, but i have tried to feed a single line… same thing. Maybe somebody can help`? PipesByLinesTest.dyn (25.0 KB) This is the code of the block: "import clr clr.AddReference(“RevitServices”) import RevitServices from RevitServices.Persistence import DocumentManager from RevitServices.Transactions import TransactionManager doc = DocumentManager.Instance.CurrentDBDocument clr.AddReference(“RevitAPI”) import Autodesk from Autodesk.Revit.DB import * clr.AddReference(“RevitNodes”) import Revit clr.ImportExtensions(Revit.Elements) clr.ImportExtensions(Revit.GeometryConversion) if isinstance(IN[0], list): lines = IN[0] else: lines = [IN[0]] FirstPoint = [x.StartPoint for x in lines] SecondPoint = [x.EndPoint for x in lines] if isinstance(IN[1], list): pipetype = UnwrapElement(IN[1]) else: pipetype = [UnwrapElement(IN[1])] ptl = len(pipetype) if isinstance(IN[2], list): systemtype = UnwrapElement(IN[2]) else: systemtype = [UnwrapElement(IN[2])] stl = len(systemtype) if isinstance(IN[3], list): level = UnwrapElement(IN[3]) else: level = [UnwrapElement(IN[3])] ll = len(level) if isinstance(IN[4], list): diameter = IN[4] else: diameter = [IN[4]] dl = len(diameter) elements = TransactionManager.Instance.EnsureInTransaction(doc) for i,x in enumerate(FirstPoint): try: levelid = level[i%ll].Id systypeid = systemtype[i%stl].Id pipetypeid = pipetype[i%ptl].Id diam = diameter[i%dl] pipe = Autodesk.Revit.DB.Plumbing.Pipe.Create(doc,systypeid,pipetypeid,levelid,x.ToXyz(),SecondPoint[i].ToXyz()) param = pipe.get_Parameter(BuiltInParameter.RBS_PIPE_DIAMETER_PARAM) param.SetValueString(diam.ToString()) elements.append(pipe.ToDSType(False)) except: elements.append(None) TransactionManager.Instance.TransactionTaskDone() OUT = elements" [image]

hi sovitek, thank you so much your concern for me to create this.god bless you. hussain

hi sovitek, i could not able to find out Openmep package in dyanamo.any clue?

Hi again yeps that package need to be downloaded here from github… [image] Releases · chuongmep/OpenMEP A package for MEP, Computational Design, Generative Design inside Dynamo Revit , Sandbox , AutoCAD, Civil3D & more - chuongmep/OpenMEP [Skærmbillede 2023-10-16 094226]

pipe to cad.dyn (65.4 KB) kindly review i did not get it correctly.kindly tell me where i did mistake.

almost there just need some crossproduct and some other small things …try as here…PS be sure you have dynamoironpythonpackage installed as well…hope it works :wink: pipe to cad.dyn (58.0 KB)

hi thanks a lot now works.i want to know why u did cross product(lacing) for geometry does intersect.shall i know.

Hi in that case we search all possible intersections…take a look here https://primer.dynamobim.org/06_Designing-with-Lists/6-1_whats-a-list.html

here is a great one as well… [05 - Understanding lacing in Dynamo (Dec 2020)]
