Hi Mondo,
If the Template option is grayed out, I'm assuming it's because Worksharing was enabled. Unfortunately it is not possible to create a template file from a workshared project.
Some options from this point would be:
To transfer as much data as possible into a non workshared file, and then save that file as the template:
Link the other project in, Bind the link, and ungroup the group that results from the bind. This should bring all of the geometry from the other file into the new one.
Use Manage > Transfer Project Standards to transfer any additional family types, line weights, materials, view templates, and object styles into the new file.
To copy Legends from one project to another:
To copy schedules, reports, drafting views, and drafting sheets that do not contain model views:
You can also Copy elements to the Clipboard and Paste them into the new file.
Another option would be to use this project as a template without saving it as an RTE. Instead, open the file, and use Save As to save it as a new Central to start a new project.
I hope this helps!
You can open the model detached, and discard worksets. Then you can save-as a project template.
Effectively, you can't have your template drive workset related items, which is really a drop in the bucket in the grand scheme of time savings you'd get out of a proper template.
The Autodesk solution above is...kind of absurd with so many hoops to jump through, unless I'm missing something.
