Engineering graphics chapter 1 notes

Technical Drawings serve three purposes, and those include

Visualization, communication, and documentation

Graphic representation has developed along two distinct lines, being

Artistic drawing, and technical drawing

The organized and orderly approach to solving problems is known as

The design process

The design process for any product requires a clear understanding of

a products expected function and performance

one procedure for designing a new or improved produce follows these stages

Problem identification, Ideation, Refinement/analysis, Implementation/documentation

A systematic approach to integrate the design and manufacture of products with the goal of optimizing all elements in the life cycle of the product

Concurrent engineering

All aspects of a product, including development, production distribution, use, disposal, and recycling, is

the life cycle design

Engineering design stage 1

Identify the customer and the problem

Engineering design stage 2

Generate concepts/ sketch and formulate your ideas

The ability to think of complex objects in terms of their basic solid components and to identify relationships between various surfaces, edges, and vertices is basic to

Creating both hand-generated, and computer generated sketches.

rectangular objects are easy to draw using

box construction
