Developments

Compound shapes cannot be measured accurately from a two-dimensional drawing of elevation and plan, and require development, i.e. the parts opened out and flattened on one plane. Figure 346:1, 2 illustrates a typical hopper with all sides splayed, from which it will be seen that the elevational outline is correct, but the given width of both sides and ends do not allow for the actual splay or leaning outwards towards the observer which cannot be shown. To develop these true measurements first draw the plan ABCD (346:3), extend as shown by the dotted lines, draw AB, BC, CD and DA parallel to the plan at a distance equal to X and Y in 346:1, 2 and complete.
