  1. Drafting – Product Design & Architecture Pictorial Drawings – Isometric, Oblique, & Perspective

  2. Pictorial • Pictorial sketches are sketches that show height, width, and depth all in one view. There are three common types: • Isometric • Oblique • Perspective

  3. Width and depth lines are drawn at 30 degrees from the horizon line. Isometric Note one view shows height width and depth.

  4. Oblique Front view is true size and shape. Width lines are parallel with the horizon. In Cavalier Oblique depth is full size. This cube has the same height, width and depth dimensions Depth in an oblique pictorial is distorted. Easiest of the pictorials to draw. Depth lines are drawn at an angle with the horizon.

  5. Width lines are parallel with the horizon. In Cabinet Oblique depth is half size. This allows the view to look more realistic. Front view is true size and shape. Oblique

  6. Perspective • Perspective is a way to draw that shows a view of the object in the most realistic way. Vanishing points are used to guide the lines in the object to the horizon line or the horizontal line you see at your line of sight. We will discuss one and two point perspective.

  7. One Point Perspective All lines in the depth project to one point (vanishing point). The location of the vanishing point is based on your line of sight. Note: The vanishing point in this sample is chosen for demonstration.

  8. Two Point Perspective In two point perspective the depth lines converge on one vanishing point (VP2) and the width lines converge on the other vanishing point (VP1).
