Graphic comunication Flashcards
what is graphic communication
use drawings to develop ideas and to tell others how to make and object. Sharing ideas using graphics
What is the purpose of graphics
it is easier to explain using drawing than using words and we can jot down our initial ideas using drawings which can be developed
What are the rules that designers use and why do they do this and what do they use
These rules are called conventions and we do this so people will understand the drawing or idea better. we use lines dimensions and angles to describe drawings
describe the types of lines
There are threes types of lines that designers use; they come from conventions; they are outlines, construction lines and hidden detail lines.
Outlines - Dark continuous lines that indicate the outline of an object or the parts that are visible.(straight or curved)
Construction lines - Thin, feint, continuous lines that help construct other lines. (straight or curved)
Hidden detail lines - A dashed line that show the parts that are out of sight.
Why do designers draw using accurate measurements
So that engineers can use them to construct items
Meaning - dimensioning
adding accurate measurements to a drawing to give a clear and accurate description of the product
when do we use technology
- find creative and innovative solutions to new problems
- find different solutions to existing problems
- to find temporary or short term solutions in emergency situations
- solve human needs and wants
what rules must you follow when you dimension a drawing
- 3 main dimensions = length, breadth and the height
- dimension lines, continuous, light coloured used to show distance between 2 points
- have arrowheads on the end of lines
- dimensions, written above dimension lines
- all measurements in mm
what are some of the dimension tools
- Rulers - used for measurements + drawing straight lines (not for cutting with craft knife)
- Erasers - correct errors + shading
- H or HB pencil - used to draw
- Set squares or protractors - used for drawing angles
- Compass - used to draw circles
what is scale drawing
it is the method in which we draw objects bigger or smaller on a page to get more detail or to make it fit on the page
explain what it means and how to write it when I say something is 20 times smaller
you write it like this 1:20
1=the length of the drawing 20=the length it is in real life
this means that the object that is being drawn is 20 smaller on the page than it is in real life
what should always be in a scale drawing
- real size / dimension of object shown in drawing
- the measurements are in mm
- scale is always shown on drawing
