Our customer and partner, Väderstad AB, has been working with ISO GPS for a long time. To gain deeper insights into why and how they work with ISO GPS we interviewed Markus Zwörner, an expert in geometrical assurance at Väderstad AB. Below, we’ve summarized some of the key points that we believe highlight how standards like ISO GPS and AMSE Y14 can help companies.

Why do you work with ISO GPS? 

“The main advantage of ISO GPS is that it allows us to use 3D geometry from CAD models to define requirements for 2D drawings. The alternative, using linear dimensioning, isn’t as unambiguous. By implementing an international standard within a global company, we can collaborate more effectively across departments and with various suppliers.” 

“We strive to use ISO GPS as much as possible. The system is well-structured around industry needs and is consistently updated.” 

How do you select standards from ISO GPS? 

“We choose the standards that reflect the specific characteristics of our products. ISO 1101:2017 serves as the foundation for everything. Over time, smaller standards have been separated out from ISO 1101:2017. With experience, we are familiar with the most common ones, and for special cases, we consult additional standards.” 

“There are also exceptions when the existing ISO GPS rules can’t fully express the properties on our drawings. However, ISO GPS clearly outlines how to create custom rules using symbols and terminology. In this way, all of our rules are guided by ISO GPS.” 

How do you collaborate with departments that use ASME Y14? 

“As an international company, we are sending more and more drawings between departments. We increasingly assist our teams in the USA and Canada, where they use ASME Y14.5, the North American equivalent to ISO GPS. They are also looking to implement GD&T more extensively, the language of geometric specification as described in ASME Y14.5. It’s a symbolic language that fundamentally works like ISO GPS, though with some key differences. Our systems, workflows, and expertise should be aligned to the extent that we can support one another, which strengthens us as a company.” 

What challenges do you face with ISO GPS?  

“The biggest challenge for designers is managing all of the rules, which makes it easy to overlook something. With such a comprehensive standard, we build knowledge for the most common scenarios and then investigate the special cases deeper. We continuously work on broadening our designers’ knowledge and maintaining it.” 

“Today, AI Review also helps us, saving us a lot of time and reducing errors. The more you expand and incorporate AI Review, you gain not only a reviewer but also a teacher. You also achieve unparalleled efficiency in upholding your internal standards.”
