Our manufacturing organization uses multiple CAD systems - primarily CATIA V5 and SolidWorks - for different product lines and tooling design. We’re struggling with data silos and version inconsistencies when tooling data needs to be shared across teams using different CAD platforms.

The main challenges we face: tooling assemblies designed in CATIA need to be referenced by SolidWorks users, but the native file formats don’t translate well. We end up with duplicate data sets in different formats, which creates version control nightmares. When a tool design changes in one CAD system, there’s no automated way to notify teams using the other system.

We’re running ENOVIA R2020x and looking for proven approaches to establish a centralized repository that can handle cross-CAD integration effectively while maintaining proper version control. How are other organizations handling this? What strategies have worked for keeping tooling data synchronized across different CAD environments?

Cross-CAD Tooling Data Management in ENOVIA R2020x

The core architectural answer here is ENOVIA as the system of record, with neutral format derivatives stored as managed representations alongside native CAD data. Both CAD connectors push to and pull from ENOVIA rather than exchanging files peer-to-peer.

Integration Architecture

3DEXPERIENCE Native Connectors

  • CATIA V5: Use the 3DEXPERIENCE CATIA V5 Integration (formerly V5-6R connector). This publishes V5 CATProducts/CATParts directly into ENOVIA as VPMReference objects with full revision lifecycle.
  • SolidWorks: Use 3DEXPERIENCE for SolidWorks connector. Assembles into the same ENOVIA XPDM structure, storing native .sldasm/.sldprt alongside.

Both connectors surface the same Part/Document structure in ENOVIA, so a tooling assembly from CATIA V5 and a referencing assembly in SolidWorks can share parent-child BOM relationships within a single VPMReference tree.

Neutral Format Strategy for Cross-CAD Reference

Avoid relying on native-to-native translation. Instead, establish a policy: any tooling component promoted past In Work state generates a JT or STEP AP242 derivative automatically.

You can automate this via ENOVIA Business Process Services (BPS) or a custom JPO (Java Program Object) triggered on lifecycle state change:

// JPO trigger on Promote action - simplified example
public int mxMain(Context ctx, String[] args) throws Exception {
    String objectId = args[0]; // VPMReference OID
    // Invoke FCS export or external converter via MQL command
    MQLCommand mql = new MQLCommand();
    mql.executeCommand(ctx, 
        "trigger export format JT object " + objectId);
    return 0;
}

The JT/STEP file is then attached as a Derived Output document linked to the same revision — SolidWorks users consume this without touching the V5 native data. Verify exact MQL trigger syntax in your R2020x JPO Developer Guide.

Version Control and Change Notification

  • Use ENOVIA Maturity States (In Work → Frozen → Released) as the synchronization gate. SolidWorks references should only pull derivatives from Released or Frozen revisions.
  • Configure Subscription Notifications on the VPMReference type: any promotion or revision triggers email/platform notification to affected workgroups. Navigate to ENOVIA > Collaborative Lifecycle > Subscriptions to scope by product context or tooling classification.
  • Enforce “Where Used” impact analysis via Structure Browser before any CATIA-side revision is promoted — surface all downstream SolidWorks assemblies referencing the derivative.

Configuration Path

ENOVIA Admin > Business Modeler > Types > VPMReference
  > Lifecycle: Define states + trigger assignments
  > Relationships: "Derived Output" relationship to Document type

Version Compatibility Note

Connector compatibility between CATIA V5 R29/R30 and 3DEXPERIENCE R2020x is documented in the Dassault compatibility matrix — verify your specific V5 release level is certified for R2020x before deploying. SolidWorks connector support for specific SW releases (2020, 2021) against R2020x similarly requires matrix verification.

The single most impactful discipline: never allow teams to store tooling masters outside ENOVIA. The silos persist because escape paths exist.

We faced the exact same challenge two years ago. Our solution was to establish ENOVIA as the single source of truth with neutral file formats (STEP AP242) as the interchange standard. Each CAD system checks in native files plus a neutral representation. When cross-CAD access is needed, teams pull the neutral format. It’s not perfect for full editing, but works well for reference and downstream manufacturing.

The centralized repository approach is definitely the way to go. In ENOVIA, create a unified tooling classification structure that’s CAD-agnostic. Use metadata attributes to describe tooling characteristics rather than relying on CAD-specific properties. This allows both CATIA and SolidWorks teams to search and find tooling using common terminology. For visualization, invest in a good lightweight viewer that can display both formats without requiring the native CAD applications. We use 3DPlay embedded in ENOVIA for this purpose.

Version control across CAD systems requires strict governance. We implemented a policy where all tooling designs must go through a formal release process in ENOVIA regardless of source CAD system. The release workflow automatically generates derivative formats and notifications. Change management becomes CAD-neutral - when a tool changes, the ECO system notifies all affected users regardless of which CAD system they use. The key is making ENOVIA the authoritative system, not the CAD tools.

Cross-CAD integration really benefits from a well-designed data model. Create separate object types for ‘Tooling Design Master’ (CAD-neutral) and ‘CAD Representation’ (format-specific). The master holds all the engineering metadata, specifications, and lifecycle state. Each CAD system creates representations linked to the master. This way, version control operates at the master level, and all CAD representations stay synchronized through the relationship structure. Users see one logical tool with multiple physical representations.

The neutral format approach makes sense for view-only scenarios. But what about when SolidWorks users need to modify a tool originally designed in CATIA? Do you force them to work in CATIA, or allow parallel design branches? We’re concerned about maintaining design intent across translations.

8

For modification scenarios, you need clear ownership rules. We designate a ‘master CAD system’ for each tool family based on which team has primary design responsibility. If SolidWorks users need to modify a CATIA-owned tool, they submit change requests through ENOVIA’s ECO process. The owning team makes the changes in the native system, then regenerates all derivative formats. This prevents divergent design branches and maintains a single authoritative version.

Having managed multi-CAD environments for over a decade, I can share what works consistently across different organizations. The solution requires addressing all three critical areas: centralized repository architecture, cross-CAD integration mechanisms, and robust version control.

For the centralized repository, implement a three-tier data structure in ENOVIA. First tier: ‘Tooling Master’ objects that contain all CAD-neutral information - specifications, materials, manufacturing parameters, cost data. Second tier: ‘CAD Representations’ linked to the master, one for each native format (CATIA, SolidWorks, etc.). Third tier: ‘Derivative Formats’ for neutral standards (STEP, JT, 3D PDF) generated automatically during check-in. This structure ensures one logical tool exists in the system while accommodating multiple physical representations.

Cross-CAD integration requires both technical and process solutions. Technically, configure ENOVIA’s CAD integrations to automatically generate neutral formats during check-in. Use STEP AP242 for geometry and PMI, JT for lightweight visualization, and 3D PDF for manufacturing review. Process-wise, establish clear ownership rules - each tool has a designated ‘master CAD system’ based on the primary design team. Cross-CAD users access neutral formats for reference, or submit formal change requests if modifications are needed.

Version control must operate at the master object level, not the CAD file level. When any CAD representation changes, the master version increments and all other representations must be regenerated or marked as ‘pending update’. Implement subscription-based notifications so users working with derivative formats get alerted when the source changes. Use ENOVIA’s effectivity management to control which version of a tool is valid for which product line or manufacturing facility.

For practical implementation, start with a pilot tool family. Create the master objects, link existing CAD files as representations, generate neutral formats, and establish the change workflow. Train both CATIA and SolidWorks teams on the new process - emphasizing that ENOVIA is now the authoritative source, not their local CAD vaults. Measure success by tracking reduction in duplicate tooling designs and improved cross-team visibility.

This approach has proven effective across automotive, aerospace, and industrial equipment manufacturers dealing with similar multi-CAD challenges.
