Dividing existing parts with dynamo


#1

I’ve been reading and studying the post dividing parts with dynamo
As I am new to python, i’m unsure on what to amend so that it divides the internal part of the wall not the entire wall.

Additionally… I also need to then split the result horizontally (Forming panels)

Any help would be appreciated.

Thank you.

Below is the original script which I subsequently tweaked to selected the already generated part.

Tweaked script.

The embedded python script is where I’m stuck (Python newbie)

  1. import clr
    
  2. clr.AddReference(‘RevitAPI’)

  3. from Autodesk.Revit.DB import *

  4. clr.AddReference(‘System’)

  5. from System.Collections.Generic import List

  6. clr.AddReference(‘RevitNodes’)

  7. import Revit

  8. clr.ImportExtensions(Revit.GeometryConversion)

  9. clr.ImportExtensions(Revit.Elements)

  10. clr.AddReference(‘RevitServices’)

  11. import RevitServices

  12. from RevitServices.Persistence import DocumentManager

  13. from RevitServices.Transactions import TransactionManager

  14. doc = DocumentManager.Instance.CurrentDBDocument

  15. #Preparing input from dynamo to revit

  16. wall = UnwrapElement(IN[0])

  17. divisionLines = [l.ToRevitType(True) for l in IN[1]]

  18. sketchPlane = UnwrapElement(IN[2])

  19. #Create a list for the wall and the divisionLines

  20. wallList = ListElementId

  21. wallList.Add(wall.Id)

  22. intersectionElementsIds = ListElementId

  23. curveArray = ListCurve

  24. #All actions that makes changes to the Revit database needs to be inside a Transaction

  25. TransactionManager.Instance.EnsureInTransaction(doc)

  26. if PartUtils.AreElementsValidForCreateParts(doc, wallList):

  27. createParts = PartUtils.CreateParts(doc, wallList)
    
  28. doc.Regenerate()
    
  29. parts = PartUtils.GetAssociatedParts(doc, wall.Id, 0, 0)

  30. partDivide = PartUtils.DivideParts(doc, parts, intersectionElementsIds, curveArray, sketchPlane.Id)

  31. TransactionManager.Instance.TransactionTaskDone()

  32. OUT = partDivide

I would like on the selected part to be divided not the entire wall.
Any help would be appreciated.

I’ve attached the DYN partDivisionLines.dyn (47.8 KB)
