I use Smarteam and I'm sure others are the same. In the SW, you can place your templates under the System Options -> Default Templates.
If you asking about how to create them, then that's another story.
Open your Drawing than Save as a template (Save as > Drawing Template) or just copy your existing template files to the PDM. Make sure everybody can see that folder and files. And also exist as a local file for everybody. (In SolidWorks PDM you have an option for that.)
Than set this location in SolidWorks: Options > File Locations > Documents Templates.
