Which type of drawing shows the exact size and shape of all parts of complex objects?

• A. Orthographic drawing
• B. Exploded view
• C. Sectional view
• D. Isometric drawing

Answer: (A)

Orthographic drawings show the exact size and shape of all parts because they present true views of each surface (front, top, side) with precise dimensions and no perspective distortion. This means every feature can be measured directly from the drawing, which is essential for manufacturing complex objects where accuracy of each part matters. Exploded views illustrate how parts fit together but spread out the parts and don’t provide a single true-size representation. Sectional views reveal internal features by slicing the object, focusing on interior geometry rather than showing every external dimension of all components. Isometric drawings give a 3D impression with some distortion, so they aren’t used when exact sizes and shapes must be conveyed for fabrication.
