Filtering of structural columns...!?

Revit

Good morning everyone.
I’m trying to get the STRUCTURAL PILLARS that allow the placement of REINFORCEMENTS…I’m trying to find a way to do it all by PYTHON…
Using Python code.
I only need to capture those “STRUCTURAL PILLARS” that allow me to place “STRUCTURAL REINFORCEMENTS.”
What would be the method or property that allows me to perform this action?

Hi,
you can use this method

import clr
import sys
import System
from System.Collections.Generic import List
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *

clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *
from Autodesk.Revit.DB.Structure import *

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

doc = DocumentManager.Instance.CurrentDBDocument
uidoc=DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument

filterValidHost = System.Predicate[System.Object](lambda x : RebarHostData.IsValidHost(x))
GeneralColumns = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_StructuralColumns).WhereElementIsNotElementType().ToElements().FindAll(filterValidHost)

OUT = GeneralColumns

Hello, in your code, for establishing the filter (filterValidHost), is this class you are using?

Yes .Net List can be filtered with FindAll() and a Predicate

alternatively, the use of PLINQ extension remains easily possible with IronPython

import clr
import sys
import System
from System.Collections.Generic import List
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *

clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *
from Autodesk.Revit.DB.Structure import *

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

doc = DocumentManager.Instance.CurrentDBDocument
uidoc=DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument

clr.AddReference("System.Core")
clr.ImportExtensions(System.Linq)

GeneralColumns = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_StructuralColumns)\
												.WhereElementIsNotElementType()\
												.Where(lambda x : RebarHostData.IsValidHost(x)).ToList()

OUT = GeneralColumns

thanks
the filter method you are using is faster in case of a lot of elements, that’s why you are using it?
rather than this

cont=[]

TotalColumns = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_StructuralColumns).WhereElementIsNotElementType().ToElements()

for i in TotalColumns:
    if RebarHostData.IsValidHost(i)==True:
        cont.append(i)
    else:
        pass

OUT = cont,TotalColumns

I have a preference for Predicate and PLINQ extension, but it is not necessarily the fastest methods

there are some tests here
