What type of drawing shows the part before it is shaped by bending or rolling?

• A. Developed view
• B. Exploded view
• C. Isometric view
• D. Section view

Answer: (A)

The main idea here is the flat pattern that shows a sheet metal part before it’s bent or rolled. The developed view gives you the true-size layout of all surfaces on a single plane, so you can cut the sheet and then bend it into the final shape. It’s exactly what you’d use to plan and fabricate a part before forming operations. Exploded views are for showing how parts fit together in an assembly, not the flat before-formed shape. Isometric views are 3D representations that show depth and is for visualizing the finished form. Section views reveal internal features by cutting through the part.
