A traditional descriptive geometry technique where a drafter pivots an angled plane around its line of intersection until it lies flat against a primary projection plane. This allows engineers to draw the true shape and true size of an inclined surface on a flat 2D drawing. While 3D solid modeling has largely automated this process, understanding the projection logic remains essential for interpreting complex mechanical prints.
