Dimensions, Tolerance, Assemblies - Coggle Diagram

- - - - Has +/-
      - Defines how much the dimension can deviate
    - - Units (in mm) not indicated on every dimension but at the bottom corner of the drawing
      - Base Dimension
    - - Has an arrowhead on each ends
    - - Extend from the surface of the object but do not touch the object lines
      - Establish the size of the dimension by slight passing the dimension line
    - - A gap between the object line and the extension line
      - Prevents confusion with visible lines of the model
  - - - Consists of several dimensions originating from a common reference surface (also know as datum)
    - - Simplifies parallel dimensions in order to reduce the space used on a drawing
    - - Only used when the function of the object is not affected by the accumulation of tolerances
    - - Uses both parallel and chain dimensioning
    - - Placing arrowheads between such extension lines may it difficult to read
      - Arrowheads can be placed outside of the extension lines instead
    - - To dimension multiple dimensions
      - N x Dimension
    - - Radial Dimensions start with 'R'
      - Can be shown with or without a centre location on the drawing
    - - Circle is dimensioned by its diameter
      - Arc is dimensioned by its radius
      - Hole is located by its centrelines
    - - Marked with a curved dimension line
      - Has degree symbol
- - - - Allowed to vary in two directions from the specified dimension
      - Both directions need not vary by the same amount (Bilateral-equal or Bilateral-unequal)
    - - Allowed to vary in only one direction
    - - The upper and lower limits of the dimension are specified
- - - - Our Focus
      - Fixes two components to one another; it provides no degrees of freedom
    - - Has a single rotational degree of freedom, much like a hinge
- - - - Each component will now have their bodies
  - - - Using Transform in Animation Tab
