When a truss is viewed at a 90 degree angle in a cross section/elevation view, its shape can be edited. Click on the truss to select it and edit handles display on a surrounding polyline. Change the shape of this polyline and the truss regenerates inside it. Use this function to change overhang or truss end details rather than the overall truss shape.
The Lock truss and webbing attribute is set after editing so that the truss does not reshape itself back between the roof and ceiling planes the next time it is edited or otherwise changed. See "Roof Truss Specification Dialog".
