pyRevit extension to toggle point cloud visibility

[Anonymous]

I'm trying to write a basic extension to toggle point cloud visibility in the active vew as shown below. But I receive this eror... 

TypeError: bool is not callable

import clr

clr.AddReference('RevitAPI')
clr.AddReference('RevitAPIUI')

from Autodesk.Revit import DB

uidoc = __revit__.ActiveUIDocument
doc = __revit__.ActiveUIDocument.Document

view = doc.ActiveView
t = DB.Transaction(doc)
t.Start('Set Pt Cloud Color Mode')
view.ArePointCloudsHidden(False, True)
t.Commit()

Hey,

It seems like you are trying to use the property ArePointCloudsHidden as a method. If you want to switch the visibility of the point cloud, you could use the method HideCategoryTemporary.

I have developed this tool before, it is on C# but you can see the code.

or download it.

Kind regards.

My solution for hiding and showing point clouds in active view (in pyRevit script file):

from Autodesk.Revit.DB import *

doc = __revit__.ActiveUIDocument.Document
collector = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_PointClouds).WhereElementIsNotElementType()
elements = collector.ToElements()
pointclouds = collector.ToElementIds()

visible = False
for element in elements:
   if not element.IsHidden(doc.ActiveView):
      visible = True
      break

if visible:
   t = Transaction(doc,"Hide pointclouds")
   t.Start()
   doc.ActiveView.HideElements(pointclouds)
   t.Commit()
else:
   t = Transaction(doc,"Unhide pointclouds")
   t.Start()
   doc.ActiveView.UnhideElements(pointclouds)
   t.Commit()
