Dimension, Tolerance, Assembly Model - Coggle Diagram

- - - - Made out of multiple dimensions orginating from common refence surface ( Datum)
    - - Simplifies parrallel Dimensioning
        
        Reduces space used for drawing
    - - Must only be utilised if function of object is not affected by accumulation of tolerances
    - - Chain + Parrallel Dimensioning
    - - Place Arrow heads outside extension Line to make it easier to read
    - - Use N x Dimension to dimension Multiple parts
    - - Represented by Capital R
    - - Circle Dimensioned by diameter
      - Arc Dimensioned by Radius
      - Holes are located by their centreline
    - - Marked with curved Dimension Line
        
        Has the degree symbol
    - - Reduces tolerance build up
      - Improves Interchangebiltiy
      - Better Functional Accuracy
      - Simplifies Inspection
      - Clearer Drawings
      - Suitable for CNC / NC Machining
  - - - Extension Line Offset: Gap Between Object surface and extension Line
- - - - How to see it FUSION360
        
        Double Click on the Dimension Line to specify the tolerance
  - - - Allowed to vary in two dimensions. The directions does not need to be vary by the same amount
    - - Allowed to vary in only in one direction
    - - Upper and lower Limits of Dimensions are specified
- - - - It Helps to facilities collaberation between designers, engineers, etc
        
        How is this sustainable?
        
        1) Smarter Product Design through virtual interfacing
        
        2) Fewer Physical Prototypes are required
        
        More efficiency in manufacturing
  - - - 2) Each Compenet brought in are required to be orientated and located relative to other componets
    - - 1) Rigid
        
        Fixes two components to one another
      - 2) Revolutae
        
        Single rotational degree of freedom similiar to a hinge. Has ability to rotate around x, y, z axis and around an edge in model
      - 3) Slider
        
        Single translational degree of freedom, are utilised in components that slide on each other
      - 4) Cylindrical
        
        gives two degree of freedom ( 1 translational and 1 rotational)
      - 5) Pin Slot
        
        allows for two degree of freedom but components rotate on different axes
        
        E112 Module only use two
        
        Rigid
        
        Revolute
        
        6) Planar
        
        Allows for 3 degree of freedom ( 2 translational and 1 rotational)
        
        7) Ball
        
        2 degree of rotational freedom (pitch and yaw)
  - - - A focused, stripped down environment for creating / modifying single
    - - Workspace for connecting multiple individual parts using joints or rigid links without modifying the parts themselves
    - - Allows user to model parts, create parts, reference exisiting geometry and setting up relationships all in one file.
