Which type of drawing is used to interpret engineering drawings and plans?

• A. Orthographic Drawings
• B. Bar Graph
• C. Dimensions
• D. Flow Charts

Answer: (A)

Orthographic drawings present the object from multiple views (front, top, and side) with precise dimensions, allowing you to understand the exact size, shape, and how features line up in three dimensions. This multi-view approach is what engineers rely on to interpret plans and manufacture parts accurately, since a single view can’t show all details. The other options don’t fit this purpose: a bar graph conveys data quantities, not geometric information; dimensions are the numbers shown on drawings—not a drawing type themselves; and flow charts map processes, not an object’s geometry.
