Sketching Pictorial Views

In today's lecture on sketching pictorial views, I start by emphasizing the importance of correct proportion and understanding the horizon line when drawing. I then introduce the three main types of pictorial views used in drafting: perspective, isometric, and oblique. I explain why parallel projection methods like isometric and oblique are preferred over the time-consuming true perspective. Finally, I detail the specific drawing techniques for two-point perspective, the 30-degree axis lines for isometric projection, and the angle-based depth lines used in oblique projection.
