Design communication Flashcards
2D sketching
‘flat’ drawings that only show two dimensions
When is 2D sketching used
for a manufacturer
3D sketching
Drawings in three dimensions that show depth
When is 3D sketching used
to help develop ideas
Modelling
The use of a variety of materials and computer animations to demonstrate a design
When is modelling used?
testing/user feedback
Oblique drawing
a simple 3D sketch with one face square on. (diagonal lines are at 45°)
Isometric drawing
a 3D technique in which parallel lines at 30 degrees are applied to sides of a drawn object (diagonal lines are at 30°)
What are ellipses
Ellipses are squashed circles. When drawing ellipses the curve touches the middle of each side of the rectangular shape
Orthographic drawing
2D sketches that show different views
Perspective drawing
3D drawing that shows objects in proportion
What are exploded drawings
These sketches are used to explain how the components of a product fit together and how they are assembled. This allows designer and engineers to spot possible construction issues. They are drawn in isometric with lines following the isometric grid linking parts together.
Sketch modelling.
quick model, often just parts of a design, made from easy to work and low cost materials such as cardboard or foam
Mathematical modelling
the representation of a real situation but using mathematical concepts and language
What are the benefits of maths and computer simulation?
- cost effective as no physical components are used
- quick
- can speed up production
- can predict stresses and strengthen them before manufacture
