(In accordance with the ASME Y14.5-2009 standard)

Some folks will use any excuse to avoid change.  An example is:  "We can’t switch to the 2009 revision of the Y14.5 standard because we do not have all of the symbols in our CAD system."   Check out Section 3.2 from the 1994 standard:  

3.2 USE OF NOTES TO SUPPLEMENT SYMBOLS
Situations may arise where the desired geometric requirements cannot be completely conveyed by symbology. In such cases, a note may be used to describe the requirement, either separately or to supplement a geometric symbol. 

The chart below shows the symbols that have been added to the 2009 revision of the ASME Y14.5 standard.  The ASME Y14.5M-1994 standard and related standards provide a way to say what these symbols mean. 

So, why go to the 2009 revision of the Standard?  Compatibility and Clarification are the answers.  Moving to the ASME Y14.5–2009 provides many benefits and clarifications which include:

Don’t miss out on the advantages of the 2009 revision of the ASME Y14.5 standard just because your CAD software hasn’t caught up.

The video on the Premium Site will show you how each one of these symbols may be addressed using the ASME Y14.5-2009 standard.
