Oh I see, this is more for like snippets rather than a starting a new file from a predefined standard template, similar to Revit’s new project/family from template. Still useful and good to know, but not what I or the original author (as I understand) was looking for.
I just saw on the roadmap that a new from template is planned for implementation
In the meantime, I’m trying to implement this workflow that I’ve done in the past but for some reason having issues on my current version, posted here.
