The problem figure shows the top view of an object. Identify the correct elevation from amongst the answer figures looking in the direction of the arrow.
Show Hint
The plan shows three nested outlines: the outer square (lowest), the inner square (middle level) and the small rectangle on the left of the inner square (highest). Project their widths downward.
The plan shows three nested figures, which are three levels from bottom to top: the large outer square (base), a smaller square inside it (middle level) and a rectangle inside that square touching its left side (top level). The arrow looks from the bottom of the plan, so left and right stay as drawn. Step 1: The base spans the full width, so the elevation has a long low rectangle at the bottom. Step 2: The middle level is the inner square. It is set in from the base on both the left and the right, by about one fifth of the base width on each side, so it is a rectangle sitting in the middle of the base. Step 3: The top level is the small rectangle. It is about two thirds as wide as the middle level and is flush with its left side, so it is one tall rectangle on top of the left part of the middle block. Step 4: Answer figure 1 makes the middle level extend to the right end of the base, figure 2 makes it extend to the left end of the base, and figure 4 splits the top block with an extra horizontal line. Only answer figure 3 has the base, a centred middle block and a single top block flush with the left side of the middle block. Answer: (3) the third answer figure
