Extended billboard support
A new IsBillboard() flag has been added to ModelData_PMIPlane to indicate billboard behavior for PMI elements. At this stage, support for this flag is limited and depends on the specific importer or exporter being used.
For 3D PDF, export support has been added for billboarded ModelData_PMITextComponents. As a result, exported PDF files can display PMI text aligned with the viewport in compatible PDF viewers, improving readability and consistency of annotations regardless of model orientation.
For VRML, support has been implemented for importing billboard entities. This allows billboarded annotations defined in VRML files to be correctly interpreted during import, preserving their intended visual behavior in downstream workflows.
Removal of Python 3.7–3.9 support
Support for deprecated Python 3.7–3.9 packages has been removed from the distribution. These Python versions have reached the end of their active lifecycle and no longer receive regular updates, which limits the ability to maintain compatibility, performance, and security across CAD Exchanger SDK.
Starting with this release, CAD Exchanger SDK is distributed only with packages for Python 3.10 through 3.13. We recommend upgrading your environment to one of the supported Python versions to ensure continued access to new features, improvements, and long-term support.
Enum value updates
Deprecated enum values ModelData_WriterParameters::FileFormatType::Xml, Binary, and Cdxfb have been removed from the API. These legacy options are no longer supported and should not be used in new or existing integrations.
To ensure compatibility with current and future releases, please switch to the updated file format values CDX and CDXWEB. These formats replace the deprecated options and provide a consistent, forward-compatible way to control output generation when working with writer parameters.
