pyRevit extension to toggle point cloud visibility

Anonymous — Fri, 20 Aug 2021 05:13:14 GMT

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.

I hope it helps,

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()
