Technology preview of BIM viewer mode in Lab

CAD Exchanger team designed the special BIM viewer mode which allows users to view the modified product structure focused on BIM entities and access additional information about elements such as walls, floors, roofs, doors, and windows.
Updated persistence format lineup for data models
The release 3.19.0, was focused on BIM-specific updates and presented a new CDXBIM format for the storage of models. Now, there are four formats: CDX, CDXBIM, CDXWEB, and CDXBIMWEB. The first two can be used for storage of common model data and BIM data model when working on a desktop, and the rest two are intended for Web Toolkit for the same purposes.
New complex viewers examples in Web Toolkit
In 3.20, we added drawing, BIM, and MCAD viewers examples demonstrating the visualization of the corresponding data type. Each tool represents certain functions of displaying a specific type of data that makes it possible to use them separately depending on your needs
Improved redering performance for B-rep representations
Now users can enjoy faster and more responsive rendering of B-Rep models in Visualization Toolkit and Lab, even for large and complex models with a lot of bodies. The result is a smoother and more seamless workflow, which can help users to be more productive and achieve better results in less time.
Support for arm64 architecture on macOS
CAD Exchanger team is constantly striving to make all the tools accessible to everyone, so this release includes support for arm64 architecture on macOS. It means that SDK allows client applications to target Apple M1 and M2 series CPUs, and the Lab and the Batch users can run on new Apple hardware natively.
File format improvements

As always, multiple enhancements and corrections in both BIM and MCAD formats were added. These include: IFC, Revit, NX, STEP, glTF.
