The 3D figure shows the view of an object. Identify the correct view looking in the direction of arrow, amongst the answer figures.
Show Hint
The arrow looks at the long lower-left face; the left wall and the front base form one strip, the step block sits on it, and the right wall edge runs the full height.
Step 1: The object is an open tray with raised walls on the left, back and right, a stair-like step block at the front and an inclined plane (ramp) that rises from the step block towards the back wall. Step 2: The arrow points along the edges running to the upper right, so the viewer faces the long lower-left face. Left to right in the answer figure goes from the left wall to the right wall. Step 3: The left wall front face and the front face of the base slab lie in the same plane, so there is no line between them below the base top. The left wall shows only as a tall narrow strip whose inner vertical line stops at the base top line. Step 4: Above the base strip sits the step block, which gives a second horizontal line from the left wall to the right wall edge, about 40 percent of the way up. The ramp and the back wall are seen above it. Step 5: On the right, the front face of the base is stepped back, so a vertical edge appears at that joint. It lies in line with the inner vertical edge of the right wall, so a single vertical line runs from the top down to the bottom at about 80 percent of the width, and a small cell remains at the lower right. Step 6: Option (1) has all these features. Option (2) has no vertical line through the base at the right, option (3) draws the step line right across the left wall, and option (4) has the left wall lines continuing through the base and misses the joint line. Answer: (1) the figure in option 1
