Question 1 - Page 100 Why is this correspondence between directions on isometric paper and axes of the solid so effective for communicating the shape of the solid?This correspondence is effective because it creates a 1-to-1 mapping between 3D space and 2D paper. Parallelism is preserved: In a real cube, opposite edges are parallel. On isometric paper, those same edges are drawn following the exact same grid lines (/, \, |). This prevents the "distorted" look of freehand drawing. Consistent Scale: Unlike perspective drawing (where things get smaller as they move away), every unit on the isometric grid represents the same length. If you want to draw a 2 × 2 × 2 cube, you simply count 2 units in every direction. This makes it an essential tool for engineers and architects who need to measure things directly from a drawing.
