Support of 2 new format versions and DWG proxy entities, improved reliability in shape healing in CAD Exchanger 3.24.11

CAD Exchanger SDK and Lab updates

Support of new format versions

We are glad to announce the support of two new format versions: Revit 2024 and Solid Edge 2025. Detailed information on the import scope and file extensions is available in the documentation.

Support of DWG proxy entities

We now support DWG proxy entities, enabling the import and export of custom objects created by third-party AutoCAD plugins. This includes primitives such as polylines, hatches, circles, and text. 

Additionally, it covers complex ones like labels, tables, and other annotations. All of them were previously lost during conversion. The update improves handling of complex drawings and ensures better compatibility across CAD systems.

Format improvements

Take advantage of our format improvements for even better results:

• CATIA: fixed an issue when some free line segments were not imported, and fixed several crashes during the parsing of some parts.
• Creo: fixed a bug when external references with uppercase extensions were not loaded.
• DWG: improved import of different types of dimension tolerance data.
• IGES: fixed the issue with BSplines of degree 1 not being imported and improved the export of curve names.
• JT: fixed the issue with missing polygonal representations in certain models and improved import of primitive shapes.
• SOLIDWORKS: added C#, Python, Java wrappers for SLD_ReaderParameters::ImportHiddenElements.
• Solid Edge: added a new option to SLDE_ReaderParameters that manages whether hidden instances are to be imported.
• STEP: Added GeometricallyBoundedCurves option to STEP_WriterParameters::PreferredBRepRepresentationType, which allows exporting Wireframe body into GEOMETRIC_SET entity. When used, Wires are mapped to composite curves, whereas free Edges are mapped to regular bounded curves.
• VRML: improved import of normals, reducing memory consumption and fixing issues with certain models.

CAD Exchanger SDK updates

Improved reliability of shape healing

Earlier, for a small number of models, the healing process could trigger a fatal application crash. This issue has been fixed, ensuring stable and predictable behavior when repairing geometries.

Enhanced export of revolution surfaces to Eyeshot

Some revolution surfaces, such as degenerate tori, were previously exported without taking into account their geometric specifics. Now, you can handle such corner cases more accurately, ensuring proper visual representation.

There are also some minor changes in CAD Exchanger SDK. To get the full list of the 3.24.11 updates, read the CHANGES.txt file.

Manufacturing Toolkit updates

Here are the highlights of Manufacturing Toolkit 2025.3:

• PMI import support for STEP files;
• customizable import settings;
• configurable runtime logging;
• improved performance of unfolding and wall thickness algorithms.
