3DViewStation 2025.6.322: Major Update with Revit 2026, GLTF & CAD Fixes

The rapid evolution of design standards requires constant updating of import libraries. This 2025.6.322 version consolidates native compatibility with the latest versions of market-leading software, ensuring digital continuity without intermediate conversion or loss of structural data.

Support for the Latest Native Format Versions

Teams working on BIM and mechanical CAD projects benefit from immediate access to the latest proprietary format versions, essential for maintaining data flow consistency in multi-CAD environments.

• Revit 2026: Native reading of RVT files for visualization and analysis of architecture and construction projects from the latest Autodesk version.
• ACIS 2024 and 2025: Support for the geometric kernel used in many CAD solutions (AutoCAD, BricsCAD, SpaceClaim), ensuring faithful B-Rep geometry.
• 3MF Format: New importer for this 3D printing standard supported by Microsoft and the additive industry, allowing the reading of geometry, materials, and assemblies.

Improvements to JT, GLTF, and PLM Imports

Beyond new formats, existing importers have been strengthened to extract more metadata and correct specific behaviors identified in production.

• JT (Siemens): Additional loading of component attributes (#2320), enriching data available for analysis and exports.
• GLTF with Draco Compression: Support for Draco geometric compression (#2297), drastically reducing GLTF file size for Web and Augmented Reality.
• SolidWorks: Correction of missing PMI loading (#2268), restoring visibility of critical technical annotations.
• PLMXML (Siemens Teamcenter): Addition of references as attributes (#2318, #2391) and improved support for various XML header variants, stabilizing the import of complex PLM structures.

Complete Overhaul of GLTF Export for 3D Web

3D visualization on the Web, mobile augmented reality, and immersive experiences rely heavily on the GLTF format. The exporter has been restructured to offer maximum flexibility depending on the use case.

• Standard .gltf Format: JSON + separate binary files and textures, optimal for development and debugging.
• Binary .glb Container: All data in a single binary file, ideal for Web sharing and mobile applications.
• Embedded GLTF: JSON with base64 encoded textures, simplifying distribution without external dependencies.

Reliable Vector and VSXML Exports

• Vector Export (PDF, SVG, DXF): Support for coordinate systems (#2309) and correction of callout text positioning (#2236), improving the compliance of automated drawings.
• VSXML: Corrected writing of file paths (#2313), eliminating reloading errors in automated workflows.

Measurement functions, geometric analysis, and section creation are at the heart of design reviews and quality controls. This version enriches these tools with new visual capabilities and ergonomic fixes.

Automatic Hatching in Sections

Adding hatching to section planes (#1890) meets a recurring demand from mechanical engineering departments. Sections now automatically generate configurable hatching patterns, improving the readability of technical drawings and compliance with drafting standards (ISO 128, ASME Y14.2).

Drill Hole Center Coordinates

The automatic hole calculation function now explicitly displays the Cartesian coordinates of the center of each detected circle (#2289). This information facilitates dimensional control operations, machine tool programming, and CMM (Coordinate Measuring Machine) metrology.

Ergonomic and Interface Fixes

• Section Export Format Memory (#2328): The section dialog box saves the last used vector format (PDF, SVG, DXF), speeding up repetitive exports.
• Distance Measurement (#2367): Correction of an initial translation issue affecting multilingual display of results.
• Physical Properties (#2279): Correct automatic update of properties (volume, mass, center of gravity) during selection by color.
• Delete Invisible (#2390): The algorithm now works even when perspective rendering mode is active, eliminating an annoying limitation.

Handling massive assemblies with thousands of PMI annotations and components requires targeted optimizations. This version significantly improves loading times and corrects several critical geometric calculations.

Accelerated Loading of Annotated Models

The import of 3DVS files containing a large number of PMIs (Product Manufacturing Information) has been optimized (#2389). Internal tests show an opening time reduction of up to 40% on heavily annotated models (over 500 annotations), significantly improving the fluidity of design reviews.

Reliable Geometric Calculations

• Minimal Bounding Box (#2336): Restoration of optimal bounding box calculation performance, essential for packaging optimization and footprint analysis.
• Collision Detection (#2218): Correction of penetration depth calculation, improving the accuracy of interference analysis in mechanical assemblies and assembly studies.

Printing and Configuration

• Multi-Document PDF Printing (#2330): Merging pages when printing multiple documents loaded simultaneously now works correctly, simplifying the generation of composite technical files.
• Application Settings (#2277): The de>default.xml configuration file is now correctly applied at startup, restoring the reliability of standardized enterprise deployments.

The WebViewer and Automation Server versions benefit from specific fixes to enhance security, improve 3D display in the browser, and ensure reliable batch conversion workflows.

WebViewer Security

By default, the WebViewer now prevents attempts to exit the authorized model directory (#1532), preventing uncontrolled navigation risks in the server tree structure (path traversal). This measure strengthens the security of intranet and extranet deployments.

Web Display and Transparency

A visibility issue with internal parts when applying transparency to external components has been fixed (#2311). The WebGL rendering engine now correctly manages the drawing order of transparent surfaces, eliminating annoying visual artifacts in online design reviews.

Automation Server (KAS)

The automation server's de>CONVERT_AND_EXECUTE_XML command now fully respects specified conversion parameters (distortion, visibility, instancing) (#2249). This fix ensures the predictability of batch conversions in automated PLM/ERP publishing chains.

License Management (VSLM)

The network license management module has been improved to better count and display access denials, facilitating the sizing of license pools and the identification of bottlenecks.

What are the main benefits of this update?

This version brings three major benefits: immediate compatibility with the latest market formats (Revit 2026, ACIS 2025), modernized 3D Web export capability via GLTF, and significant reliability improvements for PLM and CAD imports with over 30 targeted fixes.

Does Revit 2026 support include families and annotations?

Yes, the Revit importer loads 3D geometry, family hierarchical structure, IFC properties, and native annotations, allowing complete visualization of BIM projects without having Revit installed.

Does GLTF export preserve metadata and assembly structure?

The GLTF exporter preserves component hierarchy, part names, and material properties. Extended metadata can be integrated via the embedded format or in associated JSON files depending on your workflow.

Is version 2025.6.322 compatible with my existing automation scripts?

Yes, backward API compatibility is maintained. The KAS fix (#2249) even improves the reliability of existing scripts using de>CONVERT_AND_EXECUTE_XML without requiring modification.
