2PictorialPictorial sketches are sketches that show height, width, and depth all in one view. There are three common types:IsometricObliquePerspective
3are drawn at 30 degrees from IsometricNote one view showsheight width and depth.Width and depth linesare drawn at 30 degrees fromthe horizon line.
4Oblique Front view is true size and shape. Width lines are parallel with thehorizon.In Cavalier Oblique depthis full size. This cubehas the same height, widthand depth dimensionsDepth in an obliquepictorial isdistorted.Easiest of the pictorialsto draw.Depth lines are drawnat an angle with thehorizon.
5Oblique Width lines are parallel with the horizon. Front view is truesize and shape.Width lines areparallel with thehorizon.In Cabinet Oblique depthis half size. This allows the viewto look more realistic.
6PerspectivePerspective 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.
7One Point Perspective All lines in the depth project to one point (vanishingpoint). The location of thevanishing point is basedon your line of sight.Note: The vanishingpoint in this sampleis chosen fordemonstration.
8Two Point Perspective In two point perspective the depth lines converge on onevanishing point (VP2) and thewidth lines converge on theother vanishing point (VP1).
