PICTORIAL DRAWING
WHAT IS IT?
2. Pictorial Sketches
• A Pictorial drawing is a view of an object as it would be
seen by an observer who looks at the object either in a
chosen direction or from a selected point of view.
• Pictorial drawings often are more readily made and
more clearly understood than are front, top, and side
views of an object.
3. Oblique Drawing
• Cavalier Oblique drawings, all lines (including
receding lines) are made to their true length.
45°
4. Oblique Drawing
• In Cabinet Oblique drawings, the receding lines
are shortened by ½ their true length to
compensate for distortion and to approximate
more closely what the human eye would see.

8. Isometric Drawings
• Isometric drawing is method of graphic
representation of 3D objects. The technique is
intended to combine the illusion of depth, with
the undistorted presentation of the object's
principal dimensions.

12. Drawing Steps – Isometric
Drawing
•
Draw border
•
Draw title block
•
Draw the horizontal baseline
•
Draw in 30° lines from a point on the baseline
•
Draw in construction box
•
Use construction lines to draw in part details then
darken lines
13. Perspective Drawing
• In Perspective Drawing objects are drawn smaller as
their distance from the observer increases. The lines of
an object are aligned to 1,2 or 3 vanishing points.
