Template drawings are actually used for different types of drawings. One being for the 3D drawings themselves the other is for Ortho drawings. For the 3D source drawings you usually don’t need to worry about too much. Maybe setup your AutoCAD® grid and snap and some other standard AutoCAD® settings.
More important are the drawing templates for your deliverables in this case for your Orthos.
The drawing template which will be used when creating a new drawing are set under Paths.
There are also drawing templates for Isos, but they are defined in the Isometric DWG Settings of Project Setup.
Like with AutoCAD® P&ID you can define the drawing template any way you want and use the Field command again to have the title block filled out with Project and Drawing properties.
