Simplifying Creo envelope geometry with SF SIMPLIFY – protecting know-how

Simplifying Creo Envelope Geometry: Why it is essential

Reduce IP cleansing time by up to 90 %

SF SIMPLIFY for PTC Creo automatically generates filled envelopes – sensitive design content is reliably removed, whilst the external geometry is preserved exactly. The tool is suitable for all manufacturing companies that need to share CAD models securely with suppliers, customers or partners. It reduces IP cleansing time by up to 90 % compared with manual methods.

In modern industrial production, manufacturers, suppliers and partners exchange CAD models on a daily basis. This poses a significant risk: anyone who shares a complete 3D model is, at the same time, revealing their entire design know-how – from manufacturing processes and component geometries right through to development details.

For IT managers and digitalisation officers in manufacturing companies, the automated generation of envelope geometries in PTC Creo is therefore a strategic necessity. It protects intellectual property without hindering collaboration with partners – and all at the touch of a button.

IP protection

Sensitive design and development data is completely removed before the model leaves the company.

Process efficiency

No need to manually select details to be removed – SF SIMPLIFY automates the entire IP clean-up process in Creo.

DMU & AR/VR

Very large assemblies can be processed considerably faster and more reliably in digital mock-up or VR environments using lightweight models.

Ability to integrate

SF SIMPLIFY integrates seamlessly into the Windchill approval process and enables fully automated conversion via UniversalWORKER.

Simplifying Creo envelope geometry: SF SIMPLIFY in detail

How the envelope geometry is generated

SF SIMPLIFY analyses the existing Creo model and uses it to automatically generate a closed envelope that precisely represents the external geometry of the component or assembly. All internal details – bores, cavities, functional elements and tolerance information – are completely removed in the process. The result is a geometrically precise model with all internal details stripped away.

In practice, companies have so far had to rely on labour-intensive manual processes: designers had to select individually which features were to be removed, a process that is not only time-consuming but also prone to errors. SF SIMPLIFY replaces this manual step with a fully automated workflow that delivers reproducible results of consistent quality.

Areas of application and use cases

SF SIMPLIFY is suitable for all companies that need to share CAD models externally, make them available as product libraries, or optimise them for computationally intensive visualisation applications. The simplified meshes are particularly suitable for:

Supplier-customer communication with protected model content
Digital Mock-Up (DMU) with large assemblies
Virtual Reality (VR) and Augmented Reality (AR) applications
Audit-proof product libraries for third-party systems
Automated model release via Windchill UniversalWORKER

Thanks to its fully automated process, SF SIMPLIFY reduces IP clearance time by up to 90 % compared with manual methods. Companies with extensive product portfolios benefit directly from shorter approval cycles and a significantly reduced workload.

Integration into existing PLM processes

SF SIMPLIFY can be integrated directly into the Windchill-based approval process. Via SF UniversalWORKER, the generation of envelope models is triggered fully automatically as soon as a model reaches a defined approval status. The lightweight models generated are stored in the PLM system in an audit-proof manner and are immediately available to downstream systems and partners.

Protecting know-how as a strategic pillar of digitalisation

Automated IP protection is not a stand-alone tool, but a key component of modern digital engineering strategies. SF SIMPLIFY bridges the gap between comprehensive data exchange and the protection of business-critical knowledge – and makes both possible at the same time.

General enquiries about SF SIMPLIFY

What is an envelope geometry in PTC Creo?

An envelope geometry (envelope) is a simplified 3D model that accurately represents the external shape of a component or assembly without revealing any internal design details. It is used to share CAD models securely with external partners without compromising the company’s intellectual property.

How can I automatically simplify Creo models for sharing?

SF SIMPLIFY fully automates the creation of envelope bodies in PTC Creo: the tool analyses the original model, removes all internal details and, at the click of a button, generates a cleaned-up model whilst precisely preserving the external geometry. No manual intervention or feature selection is required.

By what percentage does SF SIMPLIFY reduce the IP cleansing time?

SF SIMPLIFY reduces IP clean-up time by up to 90 % compared with manual methods. Instead of hours of manual work per model, the automated process takes just a few minutes – regardless of the assembly’s complexity.

For which applications are lightweight models required in Creo?

Lightweight models are primarily required for digital mock-ups (DMU), virtual reality (VR) and augmented reality (AR), where very large assemblies need to be processed efficiently. They are also used in communication with suppliers and in the creation of audit-proof product libraries for third-party systems.

Can SF SIMPLIFY be integrated into the Windchill approval process?

Yes, SF SIMPLIFY can be integrated directly into the Windchill-based approval process. Via SF UniversalWORKER, the generation of envelope bodies is triggered fully automatically as soon as a model reaches a defined approval status – without the need for manual intervention.

Is the external geometry preserved exactly when generating an envelope?

Yes, the external geometry of the original model is preserved exactly when generating an envelope model using SF SIMPLIFY. Only internal design details such as bores, cavities and manufacturing features are removed – the resulting model is geometrically accurate and continues to fit within higher-level assemblies.

Which companies is SF SIMPLIFY suitable for?

SF SIMPLIFY is aimed at all manufacturing companies that need to share CAD models externally, make them available as product libraries, or optimise them for computationally intensive visualisation applications. The tool is particularly well suited to companies in the mechanical engineering, automotive and electronics sectors that use PTC Creo and Windchill.

How does SF SIMPLIFY differ from manual simplification methods in Creo?

With manual methods, designers in Creo have to select and remove each feature individually – a time-consuming and error-prone process. SF SIMPLIFY replaces this step with a fully automated workflow that delivers reproducible, consistent-quality results and does not require specialist CAD knowledge for the clean-up process.
