Directions: The 3 - D problem figure shows a view of an object. Identify the correct front view, from amongst the answer figures, looking in the direction of arrow.
Show Hint
Looking along the arrow you see the faces that point towards you; build the outline from the tall block, the low front block and the bar on top, then mark the nearer faces inside it.
The object is made of three parts: a tall block at the left, a low long block standing in front of it, and a stepped (L-shaped) bar at the top which rests on a support behind the tall block and projects towards the viewer. Looking along the arrow, the viewer is at the front, so only the faces pointing at the viewer are drawn, and the part which is nearer hides what is behind it. 1. Outline: the tall body together with its support forms the full-height lower part of the view. The bar on top adds material only on the right-hand part of the upper level, so the top-left corner of the outline is empty (a notch at the top left). 2. The end face of the bar is a square at the top right. The step of the bar is seen as a vertical line separating this square from the narrower upper strip next to the notch. 3. The end face of the low front block is a square at the bottom left. It is narrower than the tall body and does not reach the left edge; there is a small gap between the left edge of the view and this square. These features are shown only by the first answer figure: notch at the top left, square at the top right and a square at the bottom left which does not touch the left edge. The second figure has the bottom square touching the left edge and the other two figures have no notch. Answer: (1) the first answer figure
