Once you activate Autodesk Inventor LT, you can open an existing file or start a new file. Templates are available on the Application menu 
New. You can choose from several templates with predefined units.
You can create a part or drawing file using the default template or a custom template that you created. Part templates set the default units of measurement, file properties, and other defaults for models. Drawing templates set the drafting standard, drawing resources, file properties, and other defaults for drawings.
