Topic 3- Modelling

Question 1

Aesthetic model

Answer 1

A model developed to look and feel like the final product

Question 2

Animation

Answer 2

The ability to link graphic screens together in such a way as to simulate motion or a process.

Question 3

Assembly drawing

Answer 3

A diagram that shows how components fit together to make a whole.

Question 4

Bottom-up modelling

Answer 4

A designer creates part geometry independent of the assembly or any other component.

Question 5

Data modelling

Answer 5

A model that determines the structures of a data

Question 6

Digital human

Answer 6

Computer simulation of a variety of mechanical and biological aspects of the human body.

Question 7

Fidelity

Answer 7

The degree to which a prototype is exactly like the final product

Question 8

Finite element analysis (FEA)

Answer 8

The calculation and simulation of unknown factors in products using CAD systems

Question 9

Formal drawing techniques

Answer 9

A type of drawing technique that has fixed rules, the most widely used being isometric projection and perspective drawing.

Question 10

Fused Deposition modelling (FDM)

Answer 10

A 3D printing technique that places melted layers of material on a bed to build up a 3D model.

Question 11

Graphical models

Answer 11

A visualization of an idea, often created on paper or through software, in two or three dimensions

Question 12

Haptic technology

Answer 12

an emerging technology that interfaces the user via the sense of touch.

Question 13

Instrumented models

Answer 13

Prototypes that are equipped with the ability to take measurements to provide accurate quantitative feedback for analysis.

Question 14

Laminated Object manufacturing (LOM)

Answer 14

A system that virtually slices a 3D CAD model into thin layers, then cuts out each layer from a roll of material using laser/plotter cutter. These layers
can then be glued in the correct order to create a 3D model.

Question 15

Mock-ups

Answer 15

A scale or full-size representation of a product used to gain feedback from users.

Question 16

Motion capture

Answer 16

The recording of human and animal movement by any means.

Question 17

Part Drawings

Answer 17

Orthographic drawings of the components of an assembly containing details just about that component.

Question 18

Perspective drawing

Answer 18

3D drawing that realistically represents an object by using foreshortening points (considers spatial arrangements)

Question 19

Physical modelling

Answer 19

The creation of a smaller or larger tangible version of an object that can be physically interacted with.

Question 20

Prototype

Answer 20

A sample or model built to test a concept or process, or to act as an object to be replicated or learned from.

Question 21

Selective laser sintering (SLS)

Answer 21

An additive manufacturing technique that uses a laser to fuse small particles of material into a mass that has a desired 3D shape.

Question 22

Solid model

Answer 22

Clear representation of the final part.

Question 23

Stereolithography

Answer 23

A modelling technique that creates 3D models layer-by-layer by hardening molecules of a liquid polymer using a laser beam

Question 24

Surface modelling

Answer 24

A realistic picture of the final model, offering some machining data. Surface models contain no data about the interior of the part.

Question 25

Top-down modelling

Answer 25

the design originates as a concept and gradually evolves into a complete product consisting of components and sub-assemblies.

Question 26

Virtual prototyping

Answer 26

Photorealistic CAD-based interactive models that use surface and solid modelling (digital mock-ups)

Question 27

Virtual Reality (VR)

Answer 27

The ability to simulate a real situation on the screen and interact with it in a near-natural way.
