lettering. Use a lettering style similar to that demonstrated by instructor and with a 4H pencil, display your first name
in the upper portion of the drawing area and your last name in the lower portion of the drawing area. Use a vanishing
point at the center of the page and connect light lines to exposed corners of each letter. Draw light horizontal lines
approximately 1” above and below vanishing point. Finish off “back” side of letters using parallel lines and arcs where
needed. Use HB pencil to darken.
11. Two-point Perspective (10 pts.)- Border your paper remembering to include full alphabet and numerals at top using block
lettering. As demonstrated by instructor, locate center of drawing area and draw a light horizon line across page. Locate
vanishing points at each extreme end of horizon line. Draw seven blocks (buildings), starting with a single vertical line
for the front corner of each building. At least one of the buildings must have its front corner line drawn below the
horizon, so the top or roof can be seen. Draw shapes with 4H and darken with HB.
Week 4 & Week 5

Week 6
15. Reading- pg. 104-113 of text on Geometric Construction
16. Shapes (see handout)- pg. 108 (1 assignment) Border your paper remembering to include full alphabet and numerals at
top using block lettering. Use diagonal method to find center of drawing area. Use diagonal method to divide horizontal
space by 4 and vertical space by 3 to produce 12 equal sized boxes. Darken lines, then find centers of each box and draw
construction lines both horizontal and vertical through centers. Use circle template and 4H to produce 2” and 1-1/2”
diameter circles on centers. Make exterior circles 2” and interior circles 1-1/2”. The first two boxes will contain 2”
circles. Produce the equilateral triangle inside the circle, but touching at the 3 vertices. Produce the square inside the
2” diameter circle, contacting at the midpoint of each side. Produce the hexagon (j) inside a 2” diameter circle. Finish
remaining 10 shapes as shown, placing the last octagon (n) inside a 2"x2" square. Label each box with the letter and name
of the shape as shown. Use 1/8" guidelines for all lettering.
Week 7 & Week 8
17. Personal Logos (10 pts.)- Border paper with standard class border. Use diagonal method to find center of drawing area.
Use diagonal method to divide horizontal space by 4 and vertical space by 3 to produce 12 equal sized boxes. In each of
the 12 boxes, come up with a different idea for a personal logo as explained by the teacher. These can be done freehand
or with tools. But they all must be neat and professional!
18. Corporate Logos- (2 pages @ 20 pts.) Reproduce four actual corporate logos (i.e., Nike, Pepsi, Intel, etc.) scaling them
up or down to fit drawing space. Border paper with standard class border. Divide two regularly bordered sheets in half
vertically through the center and put two logos per page centering each in the space. Use your tools on these. Staple and
turn in both pages together.
