Thin section sketch
Web14.11. Accurately sketch the resisting shear flow in the thin rectangular cross-section due to the shearing force acting on the left web as shown in Fig. 14.12. Hint: Replace the given load by a shearing force of the same magnitude acting at the shear center, plus a moment, so that the new load system is statically equivalent to the original load. WebThere are three kinds of break lines used in drawings. They are used to remove, or ‘break out” part of a drawing for clarity, and also to shorten objects which have the same shape throughout their length and may be too long to place on the drawing. Short and long break lines are used for flat surfaces. Cylindrical are used on rods, dowels, etc.

You can even create a Loft from one single 3D sketch containing all of the geometry needed to define profiles and guide curves.

WebThe diagonal lines on the section drawing are used to indicate the area that has been theoretically cut. These lines are called section lining or cross-hatching. The lines are thin and are usually drawn at a 45-degree angle to the major outline of the object.
