To construct the shadow of the segment AB of a straight line to the plane, it is sufficient to construct the shadows of points A and B on this plane and connect them with a straight line.
Shadow A t B t from segment AB , falling on intersecting planes P 1 and P 2 , has a break point C t lying on the line of their intersection ( x axis), which is also the intersection point of the shadows of the segment on each of the projection planes A t B ' t and A' t b t
Building a shadow of a straight line AB in general on the model.
