Support of 4 new format versions and SOLIDWORKS assembly features, import of STEP models without explicit product structure in CAD Exchanger 3.24.13

CAD Exchanger SDK and Lab updates

Support of Creo 12, Inventor 2026, NX 2506 and Revit 2025

We continuously update our support for proprietary file formats, ensuring you can import the newest versions and collaborate seamlessly. From this release, you can read Creo 12, Inventor 2026, NX 2506, and Revit 2025. Check out the documentation to know more about the import scope and file extensions.

Support of SOLIDWORKS assembly features

Previously, when importing assemblies with instance-specific modifications like different hole patterns on the same part, CAD Exchanger would randomly selects one geometry variant. Now it fully preserves all assembly-level features — you get exactly the design intent from SOLIDWORKS, with every cut, hole, and modification correctly represented in each instance. No more lost features or inconsistent geometry.

Import of STEP models without explicit product structure

When you import STEP files, now CAD Exchanger automatically handles geometry-only files. If your file contains a single part without product structure, we'll reconstruct the proper hierarchy for you — so you can successfully import files that previously weren't supported at all.

Format improvements

Maximize your results with our updated formats:

3D PDF

• X3DPDF_Reader now supports 3D data in PRC (ISO 14379) format.

3D XML

• Fixed a crash during conversion of empty poly representations.

ACIS

• Fixed a crash caused by incorrect parsing of some edges.

CATIA

• Fixed missing curves due to bad approximations.
• Fixed import errors and crashes during property conversion.
• Fixed a crash during parsing of spec links.

Creo

• Enabled import of Creo 12 files.
• Fixed conversion of arcs, cone surfaces, and PMI notes.
• Fixed a crash during color conversion.

DWG

• Implemented import of MLeader and QLeader into ModelData_DrawingLeader.

IFC

• Fixed a parsing issue where some property fields couldn't be read.

Inventor

• Enabled import of Inventor 2026 files.

JT

• Improved import of 2D Text Data Collection entities.
• Fixed issues with poly representations and invalid ModelData_PMIData.

NX

• Enabled import of NX 2506 files.
• Fixed a bug with extra curves and points being imported.

Revit

• Enabled import of Revit 2025 files.
• Improved support for Revit 2024 files.

SOLIDWORKS

• Added support of assembly features.
• Fixed missing instance name suffixes.
• Fixed crashes during PMI conversion and file storage parsing.

STEP

• Implemented import of models saved without an explicit product structure.
• Fixed issues with string escaping and line breaks in control structures.

CAD Exchanger SDK updates

Improved stability of C# visualization examples

We have resolved an issue where some C# visualization examples would cause access violation exceptions on exit. Previously, while the example would execute normally, it would cause an exception to you as soon as it began to terminate. Now you can run these examples smoothly from start to finish without any crashes.

More stable integration with Unity

The crash occurring when loading particular models with mesh optimization enabled in Unity has been fixed. The fix addresses stability issues during model import, ensuring reliable operation with optimization settings activated.

Manufacturing Toolkit updates

Here are the highlights of Manufacturing Toolkit 2025.5:

• support of NURBS-to-analytical recognition;
• model thumbnail generation functionality;
• enhanced the side detection algorithm in Unfolder;
• 6 new examples demonstrating key capabilities of Manufacturing Toolkit;
• updated documentation design.
