 Line thickness should also be addressed when creating a new drawing.  The default line thickness is 0.00mm and results in a hairline on a printed page.  General practices may vary by drawing type; technical, arcitectural, etc, and by drawing size; larger drawings utilize thicker lines.  A variety of sources can be found on the internet by searching for "CAD standards".  The following table provides suggested line widths for ISO A4/A3/A2 or ANSI A/B/C paper sizes:
