An additional Player object provides the controls for playing the animation. See the Programming Guide and samples for a basic introduction into constructing and playing an animation.
Physically Based Rendering
Physically Based Rendering (PBR) is now supported, enabling application developers to provide enhanced rendering realism by calculating the natural interaction of light and materials. PBR materials are created automatically for GLTF files converted using the underlying HOOPS Exchange API. Currently supported parameters include color, alpha mode, metallness, roughness, emissive factor and image based lighting.
Point attributes
Add attributes to point entities using the new API function SC::Store::AssemblyTree::AddPointAttribute. The same attribute types supported on Faces and Edges are now supported on Points.
Improved error reporting in Converter
Improvements to error reporting in file conversion. Error conditions are reported for incorrect syntax, invalid license, import failure, export failure for each possible output format. Errors are reported separately for each individual output file failure. See a full list in the Converter Command Line Options page of our API Reference.
Functional changes
PMI is no longer forced to black in 2d drawing sheets. This was the intended behavior previously, but a logic error in the code was preventing this from happening.

Linux Compiler Update. The Linux binaries for Communicator's server and authoring tools are now compiled with GCC 6.3.1 (specifically, the version from devtoolset-6 6.1 on CentOS 6.9) with -std=c++11. Please note that we are not using the C++11 ABI that is used by default by GCC 5 and later, so code that calls functions in libconverter (and probably any other code that interacts with that code) needs to be compiled with the -D_GLIBCXX_USE_CXX11_ABI=0 flag. Using this flag can prevent the compiler error detailed at the bottom of the FAQ page.
Enhancements
WebAssembly Support. The HOOPS Web Viewer is now available as a WebAssembly module. This change should improve overall performance of the Web Viewer and reduce the library size. The asm.js engine is still supported, primarily as a fallback when WebAssembly isn't available.

2D DWG Support. We now support DWG Drawings as one of the input formats available with a license that includes
full Exchange Import. Support for DWG Drawings is currently in Beta and comes with the following restrictions:
- Only 2D DWGs are currently supported. If there is any 3D geometry in the DWG file it will not be displayed. The current plan is to support 3D DWG's with the 2018 release of Communicator.
- Model View Layouts are not supported in this release which means that only the explicit sheet layouts within a drawing can be viewed in the SP1. We plan to remove this restriction in the SP2 release of Communicator scheduled for mid August.
- PNG Image Export for drawings is currently not supported.
- Minor style issues with some drawings.
- --output_html command-line option to generate self-contained HTML file which wraps the Communicator viewer and the model into a single file.
- CAD View Support in Shattered Mode
Viewer
- Handle Support for manipulating scene geometry. See the HandleOperator class.
- Nav Cube Support. See View.getNavCube() and the NavCube class.
