Deck 40: Orthographic Sketching

Question 1

Describe the making of orthographic sketches.

Answer 1

The orthographic sketch is the simplest type to make of the four types of sketches. The views are developed as in any regular instrument drawing, and the same types of lines are used. The only difference is that orthographic sketches are drawn freehand. In some situations, orthographic sketches are made with sufficient quality and quantity of information that they replace the need for a mechanical or computer drawing.

Question 2

Explain pictorial drawings.

Answer 2

Pictorial drawings are very easy to understand because they show an object as it appears to the person viewing it. Pictorial drawings show the length, width, and height of an object in a single view. The use of a pictorial drawing enables an individual, inexperienced in interpreting drawings, to quickly visualize the shape of single parts or various components in a complicated mechanism.
