Hello everyone,
As you can see in the title, I am trying to copy one element instance several times at the same location. In order to do so, I looked for the command “Aligned to Same Place” in the Revit API.
I would need some aid as I do not know how to interpret that API command in a Python node. I tried to do the following with no success.
Any kind of suggestion?
Thank you so much.
import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import
clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)
clr.AddReference("RevitAPI")
import Autodesk
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
doc = DocumentManager.Instance.CurrentDBDocument
uidoc = DocumentManager.Instance.CurrentUIDocument
uiapp = DocumentManager.Instance.CurrentUIApplication
clr.AddReference("System.Core")
from System.Collections.Generic import HashSet
def tolist(obj1):
if hasattr(obj1,"__iter__"): return obj1
else: return [obj1]
# IN variables...
run = tolist(IN[0])[0]
elems = tolist(UnwrapElement(IN[1]))
# Main Code...
if run:
# Get ElementIds to list...
elemIds = HashSet[ElementId]([e.Id for e in elems])
# Set Selection (required for the postable command)...
uidoc.Selection.SetElementIds(elemIds)
uidoc.RefreshActiveView()
# Get RevitCommandId of PostableCommand...
rvtComId = Autodesk.Revit.UI.PostableCommand(PostableCommand.AlignedToSamePlace)
# Run PostableCommand...
uiapp.PostCommand(rvtComId)
OUT = "Command Has Run"
else:
OUT = "Please set Run to True"
You may want to explore using a different workflow from PostCommand, as this is still limited to a ‘run one’ process and doesn’t like being chained as part of a workflow.
Exception: Revit does not support more than one command are posted.
Using the copy and paste-aligned commands is entirely possible.
Kind of a forced-run though, as I ran once to copy then (I used + to add an input to the Paste node) and ran again to paste.

Tip: If you ever need to know the command name for something that you have just done in Revit, look in the journal files.
