Semantic definition is a key feature of Model-Based Definition (MBD) that ensures precision, clarity and regulatory compliance throughout the product lifecycle.
Creo – the leading CAD software by PTC – has been at the forefront of semantic definition throughout its history, evolving the way it delivers these features with every new version. In this article, we’ll look at four benefits of semantic definition as delivered by Creo.
1 – No more ambiguity
Ensuring that annotations are clear and consistent has always been a challenge in product design. Creo has tackled this challenge head-on by refining its semantic definition capabilities. Now, designers and manufacturers can determine the purpose of a design quickly and easily.
Creo first introduced semantic definition in Creo 4, supporting four annotation types. It also integrated semantic information with STEP AP242 standards to enhance data exchange and compatibility. Later, in Creo 7, PTC strengthened compliance with other international standards, including ISO 1101 and ASME Y14.5.
2 – A seamless digital thread
For engineering teams working across multiple software ecosystems such as CAD, PLM and manufacturing solutions, smooth data integration is essential. Creo’s semantic definition capabilities allow for easy sharing of design information between systems, ensuring a continuous digital thread from concept to production.
Creo also enables the automation of critical tasks, including tolerance analysis and process planning. This boosts efficiency by removing the need for manual checks.
3 – Compliance made simple
For manufacturers working in highly regulated industries, maintaining compliance with industry standards like ASME and ISO is a non-negotiable. Creo has continually updated its MBD features to align with global standards, ensuring that its designs remain accurate, durable and adaptable.
In Creo versions 5 and 6, PTC introduced new features to aid compliance, including semantic query features, advanced modelling concepts, data sharing and ModelCheck for MBD.
4 – Helping designers work smarter
Creo has always placed useability at the heart of what it does. Its semantic definition features are more intuitive than ever, ensuring designers spend less time on time-consuming manual processes and more time designing.
Here are some recent additions to Creo’s capabilities that make it easier than ever to create 3D models:
- Creo 8 - Improved selection methods allow for faster annotation referencing and cut down modelling time in complex models
- Creo 11 – New box, lasso and trace selection tools make it simple to capture semantic references
- Creo 11 – Enhanced cylindrical surface selection speeds up processes and smooths out workflows
By making it easy for engineers to apply, modify and manage semantic definitions, Creo significantly reduces errors and the need for revisions, so teams can focus on innovation rather than troubleshooting.
Get started with Creo
With each version of Creo, PTC makes its semantic definition capabilities even better, so you can create better products, stay ahead of your competitors and maintain compliance with global standards.
If you’re not on board with Creo, there’s never been a better time.
