Study Notes
Projection
- Orthographic drawing displays a three-dimensional object through multiple two-dimensional views.
- Commonly includes three views: front view, top view, and side view.
- Known as orthographic projection, it helps visualize complex objects clearly.
Isometric Drawing
- A specific style of drawing where angles between x, y, and z axes are all 120°.
- Does not incorporate perspective, presenting dimensions accurately.
- Represents objects in full scale for all three dimensions.
Rules of Isometric Drawing
- Horizontal edges are depicted at 30-degree angles from the horizontal baseline.
- Vertical edges are illustrated as straight vertical lines.
- Parallel lines are shown to extend infinitely without converging, maintaining their distance regardless of extension.
