Set analytical column Z Projection parameter

Yna_Db is correct, it’s read only and you need to use the SetProjection Method in a python node. Here is an example of how to use the method: element.SetProjection(AnalyticalElementSelector.EndOrTop, StickElementProjectionY.LocationLine, StickElementProjectionZ.Bottom) Here is a complete working code: [image] import clr # Import Revit API clr.AddReference('RevitAPI') from Autodesk.Revit.DB import * from Autodesk.Revit.DB.Structure import * # Import DocumentManager and TransactionManager c…

Set analytical column Z Projection parameter

@James_Washbourne Here are the relevant sections from revitapidocs: http://www.revitapidocs.com/2018/9351c377-8b05-503f-3cce-f60af42e9def.htm http://www.revitapidocs.com/2018/174346c5-e7f3-58f1-1495-3836c9f973e3.htm If you want to add the Enumerations as string inputs you can use the Enum.Parse method. [image] import clr import System # Import Revit API clr.AddReference('RevitAPI') from Autodesk.Revit.DB import * from Autodesk.Revit.DB.Structure import * # Import DocumentManager and Trans…

Location of rebar

I found another script I had written once, but forgotten about. Think it does what you want: [image] import clr clr.AddReference('RevitAPI') from Autodesk.Revit.DB import * from Autodesk.Revit.DB.Structure import * clr.AddReference('RevitNodes') import Revit clr.ImportExtensions(Revit.GeometryConversion) clr.ImportExtensions(Revit.Elements) clr.AddReference('RevitServices') import RevitServices from RevitServices.Persistence import DocumentManager doc = DocumentManager.Instance.CurrentDBDo…

Convert All Selected Linked Elements to Parts

It was just random for debugging purposes. I believe the CreateParts method returns null. If you need to return the parts, I think you have to use PartUtils.GetAssociatedParts() Yes, the script would be even easier if you can get the elements from an IN-port. Just replace the filtered element collector with IN[1] or something similar. Here is a modified version of the script: import clr clr.AddReference('RevitAPI') from Autodesk.Revit.DB import * clr.AddReference('System') from System.Coll…

Material Paint Multiple Wall Surfaces

Probably easiest to say that just about everything directly related to how your trying to paint the walls is not correct. Here’s a script that I wrote a while back for the same kind of thing that you can look at and try to evaluate how it differs from yours. This isn’t the most robust script as it will fail if you don’t have a list (single object), or you have a multi-dimensional list, or if you have a face based wall, but it should be enough to get the point across.
