Technical sketching is a necessary skill  used by
Architects, Engineers, & Contractors to communicate basic ideas
in design and construction project work.  This lesson starts
with the very elementary practice of drawing straight lines without
the aid of a straight edge.  As we progress with our straight
practice , the lesson will progress into geometric shapes such as
triangles and also drawing lines at general angles such as 45
degrees.  Proficiency in freehand technical sketching is
communicating the idea without the use of words including elements
of shading, perspective and detail.   If the student sketches
the classroom TV, does it look like a TV or a microwave?
Proficiency is communicating!  Try to understand that straight
line practice in this lesson evolves into basic geometric shapes
and then those basic straight line shapes are used to develop
circles and arcs.  Example - a square is used to develop a
