"cut" in dynamo doesnt work.

Is my dynamo wrong?

For example, why cube(898902) is not cutting a wall (898739).

Hi,

Can you send the Revit model sample you are using? 

[ralphdenhaan]

Can you try this out? Create a custom Python script node with 2x input and place this script (in CPyton3):

import clr
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *
from System.Collections.Generic import *
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument
items1 = UnwrapElement(IN[0])
items2 = UnwrapElement(IN[1])

def CutGeometry(doc, item1, item2):
    try:
        SolidSolidCutUtils.AddCutBetweenSolids(doc, item1, item2)
        return True
    except:
        try:
            InstanceVoidCutUtils.AddInstanceVoidCut(doc, item1, item2)
            return True
        except:
            return False

TransactionManager.Instance.EnsureInTransaction(doc)
if isinstance(IN[0], list):
    if isinstance(IN[1], list):
        OUT = [CutGeometry(doc, x, y) for x, y in zip(items1, items2)]
    else:
        OUT = [CutGeometry(doc, x, items2) for x in items1]
else:
    if isinstance(IN[1], list):
        OUT = [CutGeometry(doc, items1, x) for x in items2]
    else:
        OUT = CutGeometry(doc, items1, items2)
TransactionManager.Instance.TransactionTaskDone()

@ralphdenhaan 

yeah, sure 

[ralphdenhaan]

It works for me: (check out the script above and make sure its running CPython3).
