Descriptive Geometry/Edge View
Edge view is a view looking at one side of a plane. Planes in edge view are shown as lines that are the distances of the edges of the shape. To get edge view, take a view parallel to a side of a plane. Then take another view perpendicular to the new line. Alternatively, if you already have front and top views of the plane, to get an edge view you may draw - in either view - a line from one side of the plane to the other that is parallel to the folding line, transfer this line to the other view, and then take a view perpendicular to the line from that second view. Use transfer distances from the first view to get the endpoints of the plane and complete the edge view of a plane.
