Create the sketch
Next you will want to use the Polyline tool and make a shape roughly like that in the next image. It does not need to be perfect as the final shape is done with constraints. Once you have the basic shape, we will start applying the constraints. If you had Auto constraints on, some of these constraints will have been applied automatically, if not, do the following. But first make sure that you have exited the polyline tool by right-clicking or pressing twice; the mouse cursor should turn back from a cross-hair to the standard arrow cursor. (Don't press a third time or you will exit the sketch editing mode; if this happens, click on the Model tab, then double-click the Sketch element in the tree, or right-click and select Edit sketch in the contextual menu.)
