Perspective Practices, Continued Dividing lines When the problem involves finding equal division points of a plane in or receding perspective and the placement of these points is known, the problem can be area into parts solved as shown in figure 5-23. Since the points are parallel on the object, in perspective (Continued) they have the same vanishing point. To find incrementally placed horizontal points in perspective, use this table: Step Action 1 Locate a horizon line, ground line, and station point. 2 Place a vanishing point and draw a visual ray from the SP to the VP. 3 At the intersection of A and GL, measure and center the width of the first horizontal element. 4 Draw lines from each end of the first horizontal element to the VP. 5 Measure incrementally spaced horizontal elements along A to the intersection of HL. 6 Darken the outlines. Figure 5-23 shows equally spaced horizontal points. Figure 5-23.—Projecting horizontal points. Continued on next page 5-31
