Templates were mentioned in Modules 1 and 4 as they are starting files that already have settings prepopulated in order to save time and ensure consistency. Templates may have units, layers, dimension styles, title block, plot settings and more already set up in the drawing.
Open THIS FILE to explore the template used to create the Cam design in Lesson 5.03.
Check out the Layer Control Bar to see the layers that are already setup.
Next, navigate to the Layout1 mode to see the title block that is setup as well. More will be covered on Layouts and Title Blocks in the next module.
