Enhancements in CAD and Modeling Processes
Spatial Corp, a subsidiary of Dassault Systèmes, announced a significant update to its 3D software development kits on 24th April. This update, titled 2026 1.0.1, focuses on enhancements in CAD translation, data preparation, and advanced modelling workflows.
Designed to improve efficiency, the updates include expanded format support, enhanced handling of Product Manufacturing Information (PMI), and new capabilities for complex geometry processing. These enhancements aim to optimise interoperability and robustness in CAD translation, modelling, meshing, and simulation processes.
For the 3D InterOp sector, the NX reader now imports 2D drawings from NX 2412 and later versions as visualization data. Meanwhile, the glTF writer supports Draco compression, significantly reducing mesh and point-cloud file sizes.
Key Features of the Update
The STEP reader now supports graphical PMI at the assembly level. the JT reader supports semantic PMI. Updated CAD format version support includes compatibility with JT 10.11, NX 2512, and Solid Edge 2026.
Spatial has improved data preparation tools with hidden body removal for assembly models in UConnect workflows. This is applicable to formats such as Solid Edge, Revit, and mesh formats like 3MF and OBJ.
The 3D ACIS Modeler received enhancements, including the ability to create blends with conic cross-sections defined by a rho-parameter. It also improves robustness when processing multiple edge sequences, preventing overlaps and interference.
A new feature in the 3D ACIS Modeler enables checking and optional splitting of edges with self-intersections, enhancing the stability of the modelling process.
Mesh Prep for ACIS, which requires an additional license, now simplifies the pre-processing of CAD geometry for simulation workflows. The update includes improved handling of concentric faces and complex joints and branches.
In the 3D CGM Modeler, a curve self-intersection checker detects and optionally splits self-intersecting curves. This results in a wire body with the same shape as the input curve.
Further documentation improvements include new sample code for creating fillets, providing more clarity and guidance for users.
The CSM Surface Mesher and CVM Volumetric Mesher have been enhanced with mesh healing functionality, enabling robust mesh processing.
Spatial’s ongoing efforts are focused on providing high-performance solutions that optimise data preparation and advanced modelling workflows across various industries. For more details, interested parties can visit Spatial’s official website.
