Notes: on a drawing give additional information on special detail that need particular attention to for manufacturing. See Figure 7.
Tolerance Block: gives the ranges a dimension on a part can be fabricated to. The tolerance block gives these ranges in decimal, fractional, and angular forms. The rangesare in plus and minus directions of the drawing. The tolerances that need to be different from those in the tolerance block are to be noted in the dimensions of the part. See Figure 8.
