Types Of Drawing Flashcards
(25 cards)
What is a free hand sketch
2D and 3D sketches used to quickly generate a range of design ideas
What is an isometric drawing
3D pictorial drawing that focuses on the edge of an object and uses an angle of 30° to the horizontal
What is an oblique drawing
3D pictorial drawing that focuses on the edge of an object and uses an angle of 45° to the horizontal
What is an orthographic drawing
Represents a 3D object using several ( usually 3 ) 2D views. The top, side and front. It defines accurately the requirements of the component
What are exploded view drawings
Drawing that shows the component parts and the order they are assembled
What are advantages of free hand sketches
Quick and cost effective
What is a disadvantage of free hand sketches
Takes a lot of skill
What is a disadvantage of orthographic drawings
To produce or interpret them requires skill
What is a disadvantage of exploded views
Do not provide detail of each component. Requires separate orthographic drawing of each component
What are assembly drawings
Show how multiple components are assembled to make final product
The components are in the correct position unlike exploded views
What are disadvantages of assembly drawings
They do not show detail about each component. Each component requires an orthographic drawing
What are block diagrams
Uses blocks lines and arrows to represent a complex system as a diagram
What is an advantage of a block diagram
Helps show how a system or process works
What is a disadvantage of a block diagram
Does not show in detail the technical detail and workings of the content of each block in the diagram
What is a circuit diagram
Used in electrical and electronic engineering. Shows symbols of electronic components and how they are interconnected to form a working circuit
What is a flowchart
Type of block diagram where blocks are joined together using lines and arrows to show how various processes are linked together to achieve an outcome
What can flow charts be used for
Planning purposes or writing computer programs
What is an advantage of a flowchart
Visually showing how a process works
What are disadvantages of flowcharts
Takes time to learn which symbols to use
Take time to learn how to convert a flowchart into a working system
What is a wiring diagram
Simple visual representation of physical connections and layout of an electrical circuit
What do wiring diagrams do
Show how plugs, sockets and different coloured electrical wires and cables are used to interconnect electrical devices
What is an advantage of a wiring diagram
Easy to follow
What is a disadvantage of wiring diagrams
Do not show what the physical layout of the system looks like
What are working drawings
Scale drawings which act as a guide for the manufacture of a product.
Contain graphical presentation and dimensions required by manufacturer
