OverrideGraphicSettings in active view with RevitPythonShell

I am trying to override graphics of a wall in a 3D view in Revit using RevitPythonshell. I managed to make this work in Dynamo with a Python Node.

So far I have the following code;

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

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

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

from System.Collections.Generic import List


doc = DocumentManager.Instance.CurrentDBDocument

TransactionManager.Instance.EnsureInTransaction(doc)

walls = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Walls)
elements = walls.OfCategory(BuiltInCategory.OST_Walls).WhereElementIsNotElementType()


color = Autodesk.Revit.DB.Color(255,50,50)
ogs = OverrideGraphicSettings().SetProjectionFillColor(color)


for i in elements:
    doc.ActiveView.SetElementOverrides((i.Id), ogs)


TransactionManager.Instance.TransactionTaskDone()

When I run this in RevitPythonShell it does nothing. I get no error or anything. When I print doc.ActiveView.SetElementOverrides((i.Id), ogs) it returns None.

What am I missing here? I am in a 3D View in Revit which is the active view. I am starting and ending a transaction.

Here is somewhat the same code in a Python node in Dynamo node.

Solution

  • With a few tweaks your code works:

    import clr

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

app = __revit__.Application
doc = __revit__.ActiveUIDocument.Document

elements = list(FilteredElementCollector(doc, doc.ActiveView.Id))

color = Color(255,50,50)
ogs = OverrideGraphicSettings().SetProjectionFillColor(color)

t = Transaction(doc, 'Color Walls')
t.Start()
try:
    for i in elements:
        if i.Category.Name == 'Walls':
            doc.ActiveView.SetElementOverrides((i.Id), ogs)
            print 'element overridden'
except Exception as e:
    print '- Failed to override -'
    print '- ' + str(e) + ' -'
t.Commit()
