CPython3 Issue

1

had this all working fine in Iron Python, but trying to get everything moved up to Cpython3.
I’m just getting the loops from a filled region and using the outer loop to get the gross arae.

#! python3

import clr
import sys
import System

from System.Collections.Generic import *

clr.AddReference("RevitNodes")
import Revit

clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager 
from RevitServices.Transactions import TransactionManager 

clr.AddReference("RevitAPI")
clr.AddReference("RevitAPIUI")
clr.AddReference("RevitAPIIFC")

import Autodesk 
from Autodesk.Revit.DB import *
from Autodesk.Revit.UI import *
ifc = Autodesk.Revit.DB.IFC

doc = DocumentManager.Instance.CurrentDBDocument
uiapp = DocumentManager.Instance.CurrentUIApplication
app = uiapp.Application
uidoc = uiapp.ActiveUIDocument

#######OK NOW YOU CAN CODE########

e = UnwrapElement(IN[0])
i = IN[0]

myRegions = FilteredElementCollector(doc).OfClass(FilledRegion).WhereElementIsNotElementType()
a = []
for f in myRegions:
	a.append(f)

e = a[0]
	
myAreaValue = e.get_Parameter(BuiltInParameter.HOST_AREA_COMPUTED).AsDouble()
myCurveLoops = e.GetBoundaries()
x = myCurveLoops[:1]
myOuterCurveLoop = List[CurveLoop](x)
myGrossAreaValue = ifc.ExporterIFCUtils.ComputeAreaOfCurveLoops(myOuterCurveLoops)

OUT = myGrossAreaValue

So I haven’t been able to cast list back to an IList of CurveLoops - which is where the problem lies.
As noted. works fine in Iron Python. Just missing something on casting the list back properly. (Unless I really have to pull it all apart and rebuild a CurveLoop from the curves. That would be a real pain.)

Ok. Odd. Now at home, I pasted the same code into a different computer.
No error.
Of course.Go figure.
Will have to see if it works on the other computer tomorrow.
