Draw the orthographic projections for each of the following objects, given their descriptions.

Here are the orthographic projections for each problem, described in terms of blocks (where each block is $10 \text{mm} \times 10 \text{mm}$). Hidden details are indicated by dashed lines.

3.1.1

• Front View:
  • Outline: 5 blocks wide, 4 blocks high.
  • Visible features: A 1-block high base across the full width. On top of the base, from the left, a vertical section 1 block wide and 4 blocks high. From the right, a vertical section 1 block wide and 4 blocks high. In the center, a vertical section 1 block wide and 2 blocks high. The tops of these three sections are connected by sloping
