Opening Revit File in Background with Python

[ruben.romero]

I make this work but it handles one single item as input, I need a list.

import clr

clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager

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

doc = DocumentManager.Instance.CurrentDBDocument
app = doc.Application

filePath = IN[0]
modelPath = ModelPathUtils.ConvertUserVisiblePathToModelPath(filePath)

options = OpenOptions()
options.DetachFromCentralOption = DetachFromCentralOption.DetachAndPreserveWorksets

docOnDisk = app.OpenDocumentFile(modelPath, options)

OUT = docOnDisk

You need to provide a looping mechanism for each action which requires a list. In this context utilizing List Comprehension may be easiest to implement.

The structure is basically this:
‘variable = [ thingToDo for``item in list ]

You can find lots of good tutorials on this online.

Your first action which needs to loop might look like this (on my phone and my python app wont start so pardon any inaccuracies):

modelPaths = [ ModelPathUtils.ConvertUserVisiblePathToModelPath(path) for path in filePaths ]

doc = DocumentManager.Instance.CurrentDBDocument
app = doc.Application

I am working on this now too and found this post- so this will not iterate and I dont know why?

Learning how to handle background documents in Python

Hello! I am learning more Python and am having trouble working with docs- I cant iterate over a list of docs to open them all. I can open and close one doc though. Any idea why that is? [image] import clr clr.AddReference('RevitServices') import RevitServices from RevitServices.Persistence import DocumentManager clr.AddReference('RevitAPI') import Autodesk from Autodesk.Revit.DB import * def tolist(input): result = input if isinstance(input, list) else [input] return result fileP…

yeah I just made a post out of it working with documents is such a hassle lol. this is really just me learning one step of this as I need a way to get elements from an external document to copy.
