I'm (finally) coming back to this topic, and have noted your responses. Since I don't spend all day/every day working in Fusion creating dwgs, this is somewhat sporadic for me. That said: The template(s) that I created were created and stored in whatever manner was dictated by Fusion at the time of creation, specifically July 2019. I had been using the templates, one of which was a week later in creation/modification than the other, and both of them were accessible for a long period of time. Then at some point, the newer of the two was no longer accessible by Fusion, although it was still in the Create Drawing setup dialog drop-down menu. When I ran into that, the older one was still accessible and usable, and I didn't have time to worry about it. Now, neither template is accessible by the software.
I note that there is a project folder called "Libraries", which says it contains assets used by Fusion including templates (etc...). I think this appeared at some point perhaps more recently, maybe within the last year or so. Is this meant to be a common storage location for user-created templates? I scanned through it quickly and didn't see anything that looked like my templates hiding there. And, if it is meant for user-created templates, I would assume all project folders can see this(?)
In any case, can someone point me to whatever storage location is allegedly used by user-created custom drawing templates? And, has this storage protocol changed within the last year or so?
As a final note, all my systems that run Fusion are running W7 Pro. I hope that I'm not going to hear that I must upgrade all my operating systems to W10.... Any assistance welcome. Thanks --
