Hello,

Is it possible to load multiple model files with Automator? I’m getting errors about unknown packages when trying to load The .sysml file that’s referencing elements from other .sysml files: _error (reference-error): No Namespace named_

Thanks!

Tom

Never mind, I found the relevant function. (of course only after writing this post, even though I spent a while going through the documentation before..)

Hi Tom,

Yes, you can use the `collect_files_recursively()` function to quickly get a list of all `.sysml` or `.kerml` files. Alternatively, you can also manually list out the files in `syside.load_model()` function like so: `syside.load_model(["file1.sysml", "some_folder/file2.sysml"])` (the number of files is unlimited).
