- - - - Consist of several dimensions originating from a common reference surface
    - - Simplifies parallel dimensions in order to reduce the space used on a drawing
    - - Should only be used if the function of the objects would be affected by the accumulation of the tolerances.
    - - Uses both chain and parallel dimensioning
    - - Arrow heads placed outside the extension line
    - - To dimension multiple same dimension , use N x Dimensions
    - - Radial dimension start with capital 'R'
    - - A Circle is dimensioned by its diameter
      - An arc is dimensioned by its radius
      - Holes are located by their centerlines
    - - It is marked with a curved dimension line and has the degree symbol
- - - - Bilateral Tolerance
        
        allowed to vary in two directions from the specified dimension. Both directions need not vary by the same amount.
      - Unilateral Tolerance
        
        allowed to vary in only one direction
      - Limit Tolerance
        
        the upper and lower limits of the dimension are specified
