What information sources are used for the drawing and specifications that you use in your work activities?

Would this be like tolerances , Dimensions and more information and like Note on the drawing telling you how things should be done ?What information sources are used for the drawing and specifications that you use in your work activities?Drawing formats, notes, etc. are determined by the company. Unfortunately many companies don't reference any particular industry standard for this.



As far as tolerancing goes, the defacto standard accross all industries is ASME Y14.5 (used to be ANSI, but ASME took over). This defines how to tolerance, standard symbols, etc. etc. Unfortunately as far as I know there is no free version of this standard anywhere, but there are websites available that summarize it if you do a google search.
