DEPTH
(SIDE VIEW ~ FRONT TO BACK)
HEIGHT

14. Butler’s Pretty Effective Directions for creating Oblique Sketches
Step #1: Count the boxes to determine H = (height ~ up & down), W=(width ~ side to side in front) & D =(frontside to backside)
Step #2: Create the first construction box using the H & W measurement
Step #3: Now add the D dimension & you’ll have created the construction box
Step #4: Counting boxes of the object itself, start creating the corner dots
Step #5: Create the dark object lines by connecting the dots

15. Oblique Pictorials
An Oblique pictorial 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. Common oblique angles include 30°, 45°, and 60°.
45°

16. Types of Oblique Drawings
There are two types of oblique pictorials: cavalier and cabinet. The difference between the two is based on how the depth of the object is represented.
This slide is for informational purposes so the student is aware that there are different types.
Oblique Cavalier
Oblique Cabinet

17. Types of Oblique Drawings
Oblique Cavalier
Oblique Cabinet
The difference in the two is the depth of the object.

18. General Oblique
A general oblique is a type of oblique pictorial that represents an object’s width and height, but the depth can be any size and drawn at any angle.
This is the oblique the students will be drawing. This will allow students to draw the sketch or thought they have and not worry about getting the angle or depth exact.

19. Tonal Shading
Add tonal shading to two of the three views by drawing parallel lines spaced closely together.
Increase the contrast by cross-hatching the lines on the darkest face.
Tonal shading is a nice feature to use to enhance your sketch.
