Cutting Plane Lines - ISO vs ASME

[cpdpeckh]

The company I work for has design groups and manufacturing locations in the U.S., Europe and Japan. Our past practice is to use cutting plane lines per ASME standards but some of our European and Japanese design group prefer cutting plane lines per ISO.

Please suggest pros and cons for using ISO vs ASME standards for cutting plane lines.

It's not a matter of pros & cons but rather of business practices. I do not see any wrong with the European entity to use a spec that's excepted and used in there part of the world. I must admit when I run across a drawing or design from the EU or Japan it takes a while to get use to the ISO terminology. I think it's a none issue

Use the standards your company and vendors adhere to. The company in Europe and Japan can use theirs.

Pro - local manufacturers should understand it
Con - non-local manufacturers may not understand it

This applies to both ISO and ASME, and as such is a non-issue (as the others have stated) until a world-wide standard is adopted and enforced. Don't hold your breath.

When I worked for a global company, we made the decision that we would apply ISO standrads to all drawings, no matter where they were created. The lone exception was 1st angle for Europe and asia and 3rd angle for US drawings. ISO doesn't specify one over the other.

Is there any other country in the world other than the USA that does not use ISO?

Thank you all for your responses. With your input I have concluded the following:

1. Choose the standard your manufacturers understand.
2. The decision between ISO and ASME is a non-issue.
3. Most of thw world outside the USA uses ISO.

Not sure about the ISO question, but I recall there were 3 other countries besides the USA that did not use metric as their primary measuring system. go to this link:

Other than Defense Contractors, most of the many companies I've worked with have created their own drafting standards, which are bastardized versions of either ISO or ASME/ANSI. But then haven't the ISO/ASME/ANSI organzations modified their standards lately to include the other's standards?

The reason cutting plane lines are used, is to show a more detailed section that is not visible in the "other views" Front, Side, Top. These work really well in the plastics industry and foundry industry.
