Another Directly Toleranced Dimensions Tip  

   Toleranced Dimensions Still Have Their place.

Even though basic dimensions are being used today far more than in the past, there are still many appropriate applications for toleranced dimensions. Care should be taken to only use toleranced dimensions in situations where they may be verified, reproducibly, without the possibility of misunderstanding. This generally limits their use to:

  • Tangent radii
  • Some steps or depths
  • Wall and material thickness
  • Features of size that contain opposed points


Use of the dimension origin symbol clarifies the meaning of the toleranced dimension.
