n the line of intersection of ABCD and WXYZ. Problem X To find the projection of the point of intersection of a given straightline and a given plane. (Fig. 18.) Let LM be the vertical trace of the given plane and MN thehorizontal trace, and AB h& the line given by its vertical pro-jection a^6^… … OPQ. Such a line is OQ. Its vertical projection is o\^ and itshorizontal projection oq. The vertical projection o^g^ intersects the vertical projectiond^b^ at the point c\ this the vertical projection of the point wherethe line AB intersects the line OQ and .. where it intersects theplane LMN.
