Simpack 2021x.1 has currently support for REXS-versions 1.0 and 1.1. The latest version of this file-format is 1.3, which would include for example gear microgeometry and more detailed bearing models.

Is there currently development going on to add the support for these latest REXS-versions in future releases?

Currently Simpack supports only importing REXS models, but is there any future plans to include export-functionality as well?
