Python - extract the parameters of a window

1

I tried to extract the parameters of a window (height and width for area calculation).
For a window I do it with the code block, everything works:

f1
f11335×396 70.7 KB

I try with all kinds of project windows with Python:

f2
f21846×760 287 KB

I get the error in the line 31

python error
python error1629×837 173 KB

I can’t understand why
Some help will be appreciated
Thank you

Try adding these lines as part of the imports (if you haven’t already)
They will add the dynamo design script classes

clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)

Thanks for the reply
I checked and those Dynamo design script classes are there

What does the warning say?

Thanks for the reply
I don’t understand the warning… the kink

Parameter.Parameter By Name

works

You have imported both the Autodesk.Revit.DB.Parameter and Revit.Elements.Parameter classes so there may be some clashing or overwriting.
Comment out the following lines and see if that helps

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

hi, here is removing the number of variables and following Mr. Mike’s remarks
Don’t forget to put between < / >
your code


import sys
import clr
clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)
FIN=IN[0]
Stock=[]
for t in range(len(FIN)):
    t3=FIN[t]
    la=Revit.Elements.Parameter.ParameterByName(t3,"Largeur").Value
    ha=Revit.Elements.Parameter.ParameterByName(t3,"Hauteur").Value
    S=la*ha
    Stock.append([la,ha,str(round(S,2))+" m²"])

OUT = Stock

my solution:

import clr

import sys
sys.path.append('C:\Program Files (x86)\IronPython 2.7\Lib')

import System
from System import Array
from System.Collections.Generic import *

clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *

clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)

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

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

import Autodesk 
from Autodesk.Revit.DB import *
from Autodesk.Revit.UI import *

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

#------------------------------------------------------
elements = UnwrapElement(IN[0])

area_lst = []

for element in elements:
	width = element.get_Parameter(BuiltInParameter.FAMILY_WIDTH_PARAM).AsDouble()
	height = element.get_Parameter(BuiltInParameter.GENERIC_HEIGHT).AsDouble()
	area = width * height
	new_val = UnitUtils.ConvertFromInternalUnits(area, UnitTypeId.SquareMeters)
	area_lst.append(new_val)
	
#------------------------------------------------------
	
OUT = area_lst

hi, glad to hear it, all we have to do is close the topic as resolved
(choice of Design Script classes or Revit API classes that of Mr. jmark)
