1. Determine the viewing direction for the Side View

The 'Side View' arrow points from the bottom-right towards the top-left of the isometric drawing. This means we are looking at the right face of the solid.

2. Determine the maximum height of each column from the side view perspective

Looking from the right side, the solid is divided into 3 vertical columns (depth layers from this perspective):

  • Leftmost column (back of the solid): The highest block is in the back-left column, which has a height of 3.
  • Middle column: The highest block is in the middle section, which has a height of 2.
  • Rightmost column (front of the solid): The highest block is in the front-right section, which has a height of 1.

3. Draw the side view on the grid

Draw a shape on the square grid consisting of 3 adjacent columns. The left column is 3 squares high, the middle column is 2 squares high, and the right column is 1 square high. The bases of all columns should be aligned horizontally.

答案

A 2D drawing on the square grid showing a shape with 3 columns. From left to right, the column heights are 3, 2, and 1.
