I recommend using modules for templates, or copy & paste them into ScrapIt Pro X. This way you can create the template in the window (plan, section, detail...) it will be used in so you can have walls etc. in plan templates. With ScrapIt you can have all your templates organized and available all the time without having to clutter up the project file.
One trick I like is to set up templates as legends so they become part of the drawing. This is particularly handy for electrical plans and such.
I can send a sample ScrapIt file if you like. The templates themselves won't be of much use because the layers and pens etc. will all be different and the library parts are pretty much all custom. Maybe I'll make up a quick one from the stuff that comes standard with the US package.
