What type of orthographic drawings is used to show flat pieces
One view drawings
Dimensioning
Process used to describe the size of an object as well as the location of different features of a design
Assembly Drawings
Show how different parts fit together to create the entire object
Detail Drawings
Show the exact shape and size of an object
What do orthographic drawings describe
Specific ideas of an object
Why might a company have its own guidelines for drawings
Specific procedures, methods, and organization used by a companies engineer
What is the most unique part of a perspective drawing
The use of a vanishing point
Size dimension
Type of dimension that describes the length, width, and depth of an object
Location dimension
Type of dimension that shows the distance between two different features
Shape dimension
Type of dimension used to provide detailed information about the shape of features
Oblique drawing
Type of drawing that highlights one side of an object
Perspective drawing
Type of drawing that shows an object from a specific point of view
Isometric drawing
Type of drawing that used angles equal to each other and is always drawn with standard angles
Why are symbols used in engineering drawings
Used to represent different entities in a drawing they are typically used in schematic drawings
Schematic Drawings
Used to show how different parts are connected together to form a system
Why do engineers need to be able to visualize a solution
Visualizing leads to a smoother outcome and helps better understand what was wrong in the first place
In what situation do engineers use a three-view drawing
When you need to describe a rectangular object
True or False? Engineering drawings are the initial sketches of a design solution
False
Working drawing
A type of engineering drawing that shows the most complete drawing produced
Visualization
Ability to mentally see a representation of a product for which there is no physical object
What are the 5 primary line types
Construction line, object line, hidden line, center line, border line
Engineering drawing
Drawing created to communicate products that will be manufactured
What does it mean to have a drawing that is drawn at full scale
Everything on the paper is the actual size
What are two types of lines used by engineers when dimensioning an object
Extinction line, dimension line
Leader
Line with an arrow on the end pointing to the feature
