Create and identify the radii of the sheet metal elbow shown in Fig. 28-5. First draw the perpendicular lines, and then create two arcs: one with a radius of 1.5 and the other with a radius of 3. Then dimension the 90° angle and add the notes. Before you create the leaders, open the Multi leader Style Manager and change the arrowheads to dots. Add the text as shown, and save the drawing as elbow1.dwg.
