Question

Supporting Mix of ISO/DIN and ANSI/ASME Standard Suppliers/Manufacturers

Do you have to produce design data (2D Drawing, MBD packages, etc.) that supports a mix of suppliers where some want ISO/DIN standard GD&T and others want ASME/ANSI standard GD&T?  This question came up from a team at our European division that is working between Creo Parametric and Windchill and NX and Teamcenter.

I had always thought the standard was up to the company creating the content, with some understanding given to the typical standard for the majority of the suppliers being used.  Any suppliers for whom this isn't their norm would still have to follow the called out standard.

We would be curious to hear if anyone is providing content that covers both standards as part of normal process, and how (overview) you do it.

we have two formats.  one thats for ISO and one for ASME.

 

  1. when designing for known projects based in europe we will design around an ISO format
  2. when designing for known projects based in the US then we will use a ASME format
  3. if its not known where it will be fabricated then we will design based on country of use.  If its going to be used in Europe then it will default to ISO and vice versa.

 

Option 3 is the most difficult because sourcing stock sizes and even materials is different in the US vs EU.  its turned many of our projects upside down when the business cant' decide where they should be fabricating the equipment.  If material is driving design then you need to ensure that the stock size/shapes is even available in that form. 

 

But at least a start is to have two different formats that you use for where country of fabrication is known.

    At a prior company, they are US based (at the time), we were already designing in metric already. When we switched to Wildfire and Windchill, we made the decision to use ISO standards across the globe. We had plants in the US, Germany and India, designing and manufacturing parts and building sub-assemblies and even complete machines. We were sourcing some parts from China, too.

      @jchance and @BenLoosli, thank you for your inputs!  I'm slow replying on this and can't exactly "Accept as Solution" just one of your responses because both are good, confirmed what I expected, and were useful when communicating to the folks internally who were asking about this.

      I'd be curious if anyone has some radically different approach, though maybe that would get into "competitive advantage".

      Just for status, I'll mark this or flip a coin on marking one of these as a solution.

      Thanks!
