Ab. With g as centre, con-struct / on to the plane of referenceab in P. Draw a horizontal line in plane Z at the level of b,as be. Join Pe. Draw Fd, making an angle with Pe equal tothe given angle C, and meeting de in d. As de is the H.T. of a plane, it must be on the plane ofreference, which is at… … Fiff. 214.
