LiveLink™ for AutoCAD® Updates
For users of LiveLink™ for AutoCAD®, COMSOL Multiphysics® software version 5.3 includes curves and points when synchronizing and extends support to new versions of certain CAD file formats. Read more about the LiveLink™ for AutoCAD® updates below.
Support for Synchronizing Curves and Points
You can now transfer wireframe geometries when synchronizing between AutoCAD® designs and COMSOL Multiphysics® models using LiveLink™ for AutoCAD®. A wireframe approximation of the geometry is suitable for various simulations, such as when beam elements and the like can be used and when performance and memory requirements are important.

Updated Support for New CAD File Format Versions
The CAD file import and export functionality has been extended to support new versions for the following file formats:
Read from File
- Parasolid®: (.x_t, .xmt_txt, .x_b, .xmt_bin) up to V29.1
- ACIS®: (.sat, .sab, .asat, .asab) up to R25, 2017 1.0
- Inventor® assemblies: (.iam) versions 11, 2008–2017
