Now you’ll never confuse H, W & D (FRONT VIEW ~ SIDE TO SIDE) WIDTH DEPTH (SIDE VIEW ~ FRONT TO BACK) HEIGHT

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

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°

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

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

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.

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.
