Question

In Panel I of the figure below, the front view and top view of a structure are shown. Which one of the 3D structures shown in Panel II possesses the views shown in Panel I?

Correct answer (D) (iv) Solution Compare each structure in Panel II with both views in Panel I, looking along the arrows marked Front View and Top View . In the front view, the outline is the silhouette of the structure seen from the front, and every internal line is an edge where two visible faces at different depths meet. In the top view, the outline is the footprint of the structure, and every internal line is an edge where two top faces at different heights meet. A structure is correct only if it reproduces the outline and every internal line of both views. Projecting each candidate: Structures (i), (ii) and (iii) each fail to reproduce at least one of the two views: their projected front view or top view has a different outline or a different set of internal edges from those in Panel I. Structure (iv) produces exactly the front view (the stepped silhouette with its internal edges) and exactly the L-shaped top view with its internal edges. Answer: (D) (iv) Turn this into a strength.
