Types of Projection

Supplies HB (#2) or other medium grade pencil 6H or other hard grade pencil 8.5 x 11 white paper Fade-out grid sketch paper Grid templates Letter guideline template

Freehand sketches are used to communicate with others, so they should be neat and correctly prepared.

Sketch Quality To create good quality sketches, use the correct grades of lead and keep your pencil sharpened. Sketches use different line weights (thicknesses) to show the relative importance of different lines. The object you are drawing should be thick and black in the sketch so that it stands out from the dimensions, notes, and other lines. It is the subject of your drawing and should be communicated clearly.!

Sketched Lines Line patterns communicate what the line represents in the drawing Line patterns tell you information such as whether the line is hidden, visible, or a centerline Visible line Hidden line Hatcng Centerlin e Dimension Extension Leader Cutting Plane Viewing Plane Short break Long break Phantom Stitch Chain

Good Sketching Technique

Sketching Circles Box in circles and sketch shape Use light 6H pencil, darken with HB when you are satisfied with appearance Carefully locate tangencies Sketch curves first and then add straight lines tangent to them. This is easier than trying to make a curve tangent to straight lines.

Scale Sketches are not usually made to a particular scale. It is important to keep the sketch in proportion Use grid paper or estimate proportions by comparison

Sketch Large Features, Then Add Small Details u Look at overall dimensions first and lightly block in u Block in secondary details lightly u Add final details u Darken sketch

Develop Sketch by Blocking In

Enlarging Proportions Lay a grid over existing picture Draw larger grid Look at each portion of the object. How does it enter and exit each grid box. Sketch in lightly in enlarged boxes

Summary Quality is one of the most important aspects of sketching. Sketched lines should be bold freehand lines. The subject of the sketch should stand out clearly. Using the correct lead grades and good techniques for sketching will help your sketches look their best.
