just clarifying, a dwt is a template saved in autoCAD so when i start a new drawing i could use that template and a dwg is a finished drawing that i am saving?
A dwt is a template which you save preset settings. You may want to save the units setting changed over or later on in the course youbwill see when we create text styles and dimension styles you may want those saved in the template.
When you are drawing up a project or homeworks you want to save it as a dwg (autocad drawing)
