9.1 Engineering sketches and drawings speak to many audiences

Question 1

During what process is a lot of information created and transmitted?

Answer 1

A lot of information is created and transmitted in the drawing process.

Question 2

What are some different types of design drawings?

Answer 2

Design drawings include:

• sketches
• freehand drawings
• computer-aided design and drafting (CADD) models

Question 3

Describe the range and breadth of design drawing?

Answer 3

Design drawings extend from simple wire-frame drawings through elaborate solid models (e.g., three-dimensional objects that include color and perspective).

Question 4

What is the historical definition of drawing?

Answer 4

In historical terms: Drawing is the process of putting “marks on paper.”

Question 5

From the historical definition of drawing, describe what is meant by marks.

Answer 5

Marks include:

• sketches
• marginalia

Question 6

What is marginalia?

Answer 6

Marginalia are notes written in the margins.

Question 7

What are sketches?

Answer 7

Sketches are of objects and their associated functions.

Question 8

What is often contained in marginalia?

Answer 8

Marginalia include notes in text form, lists, dimensions, and calculations.

Question 9

What do drawings enable?

Answer 9

Drawings enable a parallel display of information.

Question 10

How do drawings enable a parallel display of information?

Answer 10

Drawings enable a parallel display of information as they can be surrounded with adjacent notes, smaller pictures, formulas, and other pointers to ideas related to the object being drawn and designed.

Question 11

What is a powerful way to organize information?

Answer 11

Notes next to a sketch is a powerful way to organize information.

Notes juxtaposed with sketches are certainly more powerful than the linear, sequential arrangement imposed by the structure of sentences and paragraphs.

Question 12

Note an example that demonstrates the effectiveness of the parallel display of information enabled by notes adjacent to sketches.

Answer 12

Question 13

How are graphic images used?

Answer 13

Graphic images are used to communicate.

Question 14

With whom are graphic images used to communicate?

Answer 14

Graphic images are used to communicate with:

• other designers
• the client
• the manufacturing organization

Question 15

What serves as a launching pad for a brand-new design?

Answer 15

Sketches and drawings serve as a launching pad for a brand-new design.

Question 16

What do sketches and drawings support?

Answer 16

Sketches and drawings support the analysis of a design as it evolves.

Question 17

What do sketches and drawings stimulate?

Answer 17

Sketches and drawings simulate the behavior or performance of a design.

Question 18

What do sketches and drawings record?

Answer 18

Sketches and drawings record the shape or geometry of a design.

Question 19

What do sketches and drawings communicate and with whom?

Answer 19

Sketches and drawings communicate:

• design ideas among designers
• the final design to the manufacturing specialists

Question 20

What do sketches and drawings ensure?

Answer 20

Sketches and drawings ensure that a design is complete.

Question 21

How do sketches and drawings ensure that a design is complete?

Answer 21

Sketches and drawings ensure that a design is complete as a drawing and its associated marginalia may remind us of still-undone parts of that design.
