Model for Descriptive Geometry by A. Jullien - Through a Given Point Construct a Plane Parallel to Two Given Lines

Description
The point (m, m’) on the left side of the relief is given. On the left side, two lines are given: ab’ depicted by the black string, and dc’ (black string missing). By constructing the red lines hg’ and ef’ parallel to lines dc’ and ab’ respectively, the plane PQP’ containing the point (m, m’) is formed parallel to the two given lines.
