Selecting elements through Dynamo

1

I thought it would be quite simple but I can’t find a way to make Dynamo select elements in Revit model (I want to create a list of elements in Dynamo and then highlight them in Revit). Anyone can lead me how can I highlight elements (I know how to get the list, just don’t know how to create selection).

From the Springs package

Hi,

You can also use Select in Revit in HotGear package or Element.SelectInView in SteamNodes package.

Thanks you both - Springs package solved it. I was assuming there is OOTB solution for this.

Hi !

Just curious here. Isn’t there a way to select the elements via :

DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument.Selection.SetElementIds()

in Python ?

I tried several inputs be somehow could not get it to work… (Python told me that it was expecting an ICollection[ElementID] object ; no idea what it is)

Hi Mustapha,

You need to import the System collection in RevitServices to use ICollection (ICollection)

You will find an example below :

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

clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from System.Collections.Generic import *

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

elements = UnwrapElement(IN[0])
select = []

for i in elements:
	select.append(i.Id)
	Icollection = List[ElementId](select)
	DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument.Selection.SetElementIds(Icollection)

OUT = elements
