ne point in the line of intersection is located atthe intersection of the given traces of the planes. To locate asecond point, draw in each plane a line parallel to H, so thatthese lines will intersect. The necessary and sufficient condi-tion for their intersection is that these two lines shall be… … GyLi, perpendicular to HQ, and draw the F-trace and edgeview, VXQ, of Q, making the given angle, a„ with GXLX. Drawa second ground line, GtL2, perpendicular to HR, and draw theF-trace and edge view, V2R, of R, making the given angle, «2>with Gr2L2. Assume any arbitrary distance, d. Draw the XVI,…
