What should be the first step of the procedure in sketching an aircraft wing skin repair?

• A. block in the views
• B. draw the final finish texture
• C. dimension every feature
• D. start with a rough shaded rendering

Answer: (A)

Establishing the overall geometry by block in the views sets up the drawing’s foundation. Roughly outlining the wing skin repair in the main views creates the correct silhouette, shows where the repair sits, and shows how edges and features align with the surrounding structure. This framing step ensures the proportions are right and the placement is accurate, which guides every later detail. Final finish texture would be added after the shape is defined, because texture can obscure edges and geometry you need to verify first. Dimensioning every feature comes after you’ve established stable outlines so measurements are tied to a true shape, not to an unsettled sketch. A rough shaded rendering focuses on appearance rather than establishing accurate geometry, so it isn’t the best choice to begin with when planning a repair sketch.
