Note - Make sure you place only one vertical line at places that require a vertical line. If you inadvertently place two vertical lines at the same place, it will appear visually correct because the lines overlap, but the system will mark it wrong. 0 No elements selected V (kN) 18 14 12+ 10 8 8 A 4 2 0 -2.0 No elements selected -4 -6 -8 -10 -12- -16- Add discontinuity lines and select segments to add to the canvas.
