t any point A in line LM draw AB perpendicular to LMand in the horizontal plane. It intersects the ground line at thepoint B. 24 Draw BCi perpendicular to AB and in horizontal plane. Make angle BA Ci=a. Revolve plane of triangle ABCi through 90° about AB oruntil BCi coincides with he vertical… … Let AB and CD be the two given lines. Through the line AB pass a plane parallel to the line CD. Prob. XV WX is the vertical trace and YZ the horizontal trace. Project the line CD on the plane WXYZ (Prob. XII), EF is therequired projection intersecting line AB at the point F, of which/ and f- are…
