MEASURING POINT METHOD 6!.. • From the major left and right vanishing points (VPL and VPR), draw lines through the transferred measurements along the major horizontal baselines in perspective. • The result is a perspective gridof one-foot squares on the floor or ground plane. W one-foot squares hen become too small to draw accurately, use two-foot or four-foot squares instead. • From VPL and VPR, draw lines through the scaled measurements along VML to establish asimilar vertical grid. • Over this perspective grid, you can lay tracing paper and draw a perspective view. It is important to see the perspective grid as a network of points and lines defining transparent planes in space rather than solid, opaque wa lls enclosing space. Thegrid of squares facilitates the plotting of points in three-dimensional space, regulates the perspect ive width, height, and depth of objects, and guides the drawing of lines in proper perspective.
