Construction of intersection of a straight line and a plane using a projecting plane

The line p(p',p'') and  the plane P(r1,r2) are in oblique positions in space.

Construct the intersection point P = pP, using a horizontal projecting plane that passes through p.

Images show this procedure. Click on the image to see the next step of the construction.
