GRID STEP. You can print out the base construction lines and start drawing on tracing paper or you can draw the grid layout yourself using the following steps.
1) At the top of the sheet, determine the location of the head and draw its conditional size using an oval. 2) Draw a vertical line through the middle of the head. This will be the central vertical line of the drawing. 3) From the upper border of the head, draw one segment equal to the height of the head and one segment equal to one-third the height of the head. The last one will be the upper boundary of the figure. 4) From the top of the head, draw six segments equal to the height of the head, and one segment equal to one-quarter the height of the head. 5) From the central vertical line of the figure, measure and draw: • Two segments equal to the width of the head – to the left of the line. • One segment equal to half the width of the head – to the left of the line. • Three segments equal to the width of the head – to the right of the line. • One segment equal to half the width of the head – to the right of the line. Through the boundaries of the segments we draw vertical lines. The extreme left and right segments are the vertical boundaries of the drawing.
