Topic 3- Modelling Flashcards
Aesthetic model
A model developed to look and feel like the final product
Animation
The ability to link graphic screens together in such a way as to simulate motion or a process.
Assembly drawing
A diagram that shows how components fit together to make a whole.
Bottom-up modelling
A designer creates part geometry independent of the assembly or any other component.
Data modelling
A model that determines the structures of a data
Digital human
Computer simulation of a variety of mechanical and biological aspects of the human body.
Fidelity
The degree to which a prototype is exactly like the final product
Finite element analysis (FEA)
The calculation and simulation of unknown factors in products using CAD systems
Formal drawing techniques
A type of drawing technique that has fixed rules, the most widely used being isometric projection and perspective drawing.
Fused Deposition modelling (FDM)
A 3D printing technique that places melted layers of material on a bed to build up a 3D model.
Graphical models
A visualization of an idea, often created on paper or through software, in two or three dimensions
Haptic technology
an emerging technology that interfaces the user via the sense of touch.
Instrumented models
Prototypes that are equipped with the ability to take measurements to provide accurate quantitative feedback for analysis.
Laminated Object manufacturing (LOM)
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.
Mock-ups
A scale or full-size representation of a product used to gain feedback from users.
Motion capture
The recording of human and animal movement by any means.
Part Drawings
Orthographic drawings of the components of an assembly containing details just about that component.
Perspective drawing
3D drawing that realistically represents an object by using foreshortening points (considers spatial arrangements)
Physical modelling
The creation of a smaller or larger tangible version of an object that can be physically interacted with.
Prototype
A sample or model built to test a concept or process, or to act as an object to be replicated or learned from.
Selective laser sintering (SLS)
An additive manufacturing technique that uses a laser to fuse small particles of material into a mass that has a desired 3D shape.
Solid model
Clear representation of the final part.
Stereolithography
A modelling technique that creates 3D models layer-by-layer by hardening molecules of a liquid polymer using a laser beam
Surface modelling
A realistic picture of the final model, offering some machining data. Surface models contain no data about the interior of the part.
Top-down modelling
the design originates as a concept and gradually evolves into a complete product consisting of components and sub-assemblies.
Virtual prototyping
Photorealistic CAD-based interactive models that use surface and solid modelling (digital mock-ups)
Virtual Reality (VR)
The ability to simulate a real situation on the screen and interact with it in a near-natural way.
