CONCEPTUAL MODELLING - Coggle Diagram

- - - - section is a tool to represent the interior part of an object by "slicing" it
  - - - simple depiction of 3D object
    - - components disassembled to show each of them and how they assemble together
    - - realistically represents a 3D object using foreshortening
        
        objects are smaller as distance increases
      - good for clients who do not understand orthographic or isometric drawings
      - single point perspective, two points perspective, three points perspective
    - - show how different parts go together, identify those parts in numbers through sketches
        
        annotations --> explain thinking and sketches --> quickly convey ideas
    - - such as orthogonal, isometric and exploded isometric done with great precision and mechanical aids (CAD programs)
- - - - 3d modelling softwares produce solid representations
      - fast testing and quick generation
      - material properties, measurements and external forces should be considered (volume, gravity)
      - complex geometry and more detailed view than wireframe
      - no interior details
    - - variety of database models, way data is stored and processed
        
        flat file
        
        hierarchical --> family tree connecting one owner to other hierarchies
        
        relational
        
        formally described tables
        
        object-oriented --> zoom in in each category
        
        network --> hierarchical with more owners
    - - simulate humans biomechanics and predicts human reactions
      - if sufficient space to perform taks
      - effects on performance, psychological indices, relations between oxygen intake and heart rate
      - save time and sources, test ergonomic factors, safety and physical requirements
    - - to analyse human movement
      - special markers applied to strategic points of a moving human body
      - often used for animation movies
    - - user becomes part of human simulation by connecting a human to a computer and receiving haptic perceptions
      - designer can observe user performance and design better outcome
      - when could be difficult to train real environment
    - - linking graphic elements that together simulate motion
      - add realism to CAD
      - great detail and complexity of movement
      - saves expensive errors and time
      - also conducted off-site
    - - to evaluate design performance of virtual models under load conditions (extreme temperature, weight, speed)
      - before applying to prototypes and saving money
      - cost and time effective
    - - top-down linking together components with direct relation, if one changes the other as well
      - bottom up creates parts before assembling, each independent geometry
    - - simulates products and environments mimicking real world behaviours
      - no need of physical prototype
      - modifications quickly, materials minimised and low costs
