  1. Oblique Pictorials

  2. Oblique Pictorials An Obliquepictorial starts with a straight-on view of one of the object’s faces, which is often the front face. Angled, parallel lines are drawn to one side to represent the object’s depth. The most common oblique angle is 45°. But 30°and 60° is used also. 45° 45° 45°

  3. Three questions • What is a cube? • Is object 1 or object 2 the cube? • If object 1 and object 2 have a height and width of 5 inches what would you estimate the depth to be? 1 2

  4. Oblique Pictorials Now lets check the length of each bracket

  5. Oblique Pictorials There are three types of obliquepictorials:The differences are the depth • Oblique Cavalier – full depth • Oblique Cabinet – half depth • General Oblique – depth doesn’t matter • Height and width of the front face matter the most.

  6. Types of Oblique Drawings Oblique Cavalier Oblique Cabinet

  7. Together: 5 unit cube with 45 degree depth lines • A cube in oblique cavalier with a front, top and right view 2. A cube in oblique cabinet with a front, top and right view 3. A cube in oblique cabinet with a front, top and left view 4. A cube in general oblique with small depth lines and a front, top and right view 5. A cube in general oblique with large depth lines and a front, top and right view

  8. Draw an oblique Cavalier and an oblique Cabinet 1. Draw a cube with length of 4 units, 30° depth lines, in cavalier (together) 2. Draw a cube with length of 6 units, 60° depth lines, in cabinet (together) 3. Draw a cube with length of 7 units, 30° depth lines, in cabinet (by yourself)

  9. Oblique Pictorials There are three types of obliquepictorials:The differences are the depth • Oblique Cavalier – full depth • Oblique Cabinet – half depth 3. General Oblique – depth doesn’t matter Height and width matter on the front face

  10. Pros of Cavalier and Cabinet 1. Cavalier has all dimensions correctly measured. 2. Cabinet looks more realistic.

  11. Strategy for Advanced Oblique Sketches • Draw the front most face, then draw the depth for that face. • Draw the next front most face. Then draw the depth for that face. • Continue the process until the sketch is complete.

  12. Depth of front Next Front Depth of very front Very front

  13. Convert Isometric to Oblique caviler with depth of 45 degrees, and each block has a length of 3 units (together) BEST FRONT VIEW

  14. Draw cabinet on your own Oblique Cavalier Oblique Cabinet

  15. Circles in oblique are circles
