Import of product structure

CAD Exchanger users get access to the product structure of the imported 3D files (i.e., their part-assembly hierarchy and properties of these components). CAD Exchanger 3.12.0 includes improvements to a few workflows involving the model structure. Missing external references in Creo models are now recorded and available for a query after import, just like they already are in many other formats — STEP, JT, SOLIDWORKS, etc. In SOLIDWORKS, we’ve made improvements in specific cases for component placing and import of component names.

Import of metadata

Thanks to the support of metadata (names, IDs, user-defined properties, layers, PMI), CAD Exchanger enables the integrity of such additional information as 3D model design intent, manufacturing and usage guidelines. CAD Exchanger 3.12.0 includes several enhancements of names and layers transfer within CATIA, DWG, DXF, SolidWorks, STEP, and STL files.

Improved scope and algorithm of CAD Exchanger SDK

A few years ago, CAD Exchanger SDK gained the ability to identify elements of the model’s product structure with globally unique identifiers (GUID). It allows client applications to store relationships between domain-level data and 3D parts and assemblies. In 3.12.0, the identification capabilities were expanded to B-Rep shapes, which creates possibilities for even deeper integration of CAD data into a domain model by linking various pieces of domain information to faces, edges, and vertices.

Unity plugin improvements

What’s next?

Among the other latest changes in CAD Exchanger was an expanded polylines support in FBX, glTF, and STEP; fixed data race in import and export of certain elements of Parasolid, JT, NX, Solid Edge, Solidworks, and STEP models; and many other minor bugs.
