Pictorial Drawing (Oblique Projection)

This projection shows the objects front and top surface in a three-dimensional view that include the width, depth and height and the front face is always parallel to the front plane meaning its not angled in 30 ^o.

• Oblique projection

• Isometric projection

• Perspective projection

• 3D projection

This is a oblique drawing where in all lines are drawn in full depth that includes the receding lines. Its purpose is to illustrate the objects true length. This makes an angle of 45^o and 30^o .

• Closet Oblique drawing

• Cabinet Oblique drawing

• Cavalier Oblique drawing

• Cavapoo Oblique drawing

This is a oblique drawing where drawing are drawn with reduced by typically a half of the actual depth. The angle of projection or the receding lines makes an angle of 30^o, 45^o or 60^o .

• Cabinet Oblique drawing

• Closet Oblique drawing
