LANDSCAPING We should pay careful attention to the appropriate scale of the trees we draw in elevations and section drawings. As always, the type of trees selected should be appropriate to the geographic location of the architecture. • Insmall-scale elevations, we draw the portion of tree trunks that are visible and simply outline the foliage. Draw these outlines freehand to give the foliage atextural quality. • To contrast with the light values of adjacent, overlapping, or background forms, we can give the foliage acontrasting texture and t onal va lue. • If the scale of the drawing permits and ahigh degree of t ransparency is desired, we can simply draw the branch structures of trees. The outline of foliage can be suggested with dotted or lightly drawn freehand lines. • In para line drawings. trees should have athreedimensional quality in order to comply with the principles of para line drawing. 168 I ARC HITECTURAl GRAPHICS
