t at the point i. These traces, when projected onthe original V plane, will intersect within the limits of thedrawing, making the following solution possible. Referring to Fig. 85, the plane Z is passed parallel to V andcutting X and Y. The points h and c are seen to lie on the linesof intersection… … points a and d determinethe required line of inter-section between X and Y. Case II. If neither pairof the given traces intersecton the paper, two auxiUaryplanes, one parallel to V,the other parallel to H, maybe used after the manner ofCase I. Case III. It is some-times more convenient touse an…
