In technical drawing, graphic communication is the set of visual elements used to represent a technical object, its operation and manufacturing.
These visual elements can be lines, curves, arrows, other symbols, colours and so on.
Depending on what you want to represent (operation of a technical object, manufacturing of a technical object, etc.), graphic communication can be used to produce different types of engineering drawings and diagrams.
Depending on the diagram or manufacturing drawing chosen to produce a technical drawing, different forms of representation can be used.
To represent the operation of a pair of scissors, a design plan is created.
Here are some graphic communication elements in the diagram:
- two hollow arrows representing the force to be applied to close the pair of scissors;
- two double curved black arrows representing the bidirectional rotational motion of the scissor blades;
- two black lines representing the slides and handles;
- a small black disk representing the rivet on the pair of scissors.
Graphic communication follows specific rules. In order to properly represent the manufacturing process of a technical object, its dimensions must respect a precise scale and comply with dimensioning rules.
In addition, specific measuring instruments and techniques are required.
