Technical Graphics  The Basics  Line SegmentsIt is extremely important that you can draw correct
and accurate lines in Technical Graphics, so this section covers
the basics and a few exercises on drawing straight line segments.
We use the term line segments because in the Drawing community it is accepted that a line continues in both directions to infinity. However we only draw and see a part or section of the line so we call it a line segment. Normally people just refer to a line segment as a line which is quite acceptable but it is always good to know the correct terminology.
