Additional information:

• Filling in of the provided Template (What did you do, What did you expect to see, What did you see instead, What packages or external references (if any) were used)
• Attaching the Stack Trace (Error message that shows up when Dynamo crashes - You can copy and paste this into the Github Issue)
• Upload a .DYN file that showcases the issue in action and any additional needed files, such as Revit (Note: If you cannot share a project, you can recreate this in a quick mock-up file)

I am trying to open models in Dynamo background. I wrote a python code that would do that and get the elements I want out of each model but most of the time it crashes!

Hi there, @Semamzadehei , are you opening Revit models in the background?

You will need to ensure to run Dynamo in "manual run mode" and not close the documents during your active session. If you can, please share sample files for us to test.

Background documents are very difficult to work with in Dynamo and something that I have quite a bit of experience with as the author of the Rhythm package. I would say to keep the following in mind:

1. Once you open a Revit file in the background, do not close it, until you are done using it downstream.
2. Once closed, you will need to close your Dynamo graph and reopen or you will run into an error because the document is lost.
3. If possible, do all of your actions in one node, in your case Python. If you do the open action along with any queries or changes, then close the file in one python node, it should not crash.
