• The plugin for Revit 2026 has been updated for collaboration with LIRA-CAD and LIRA-FEM 2026. Correct two-way exchange of analytical models, calculation characteristics, and the physical model via IFC has been implemented.
• Settings are now remembered in the Export to LIRA-FEM 2026 dialog. When importing an analytical model from Revit, correct formation of radial walls in LIRA-CAD is ensured according to the original Revit geometry.
• An automatic comparison tool has been implemented for Revit structural elements with the LIRA-CAD model via IFC format. This solution significantly reduces the amount of manual matching of sections, thicknesses, and geometry changes of structural objects, and ensures correct display of this data in Revit.

Autodesk Revit 2025 and LIRA-FEM are integrated via a two-way converter. Thus, there is full data exchange between the programs. As a result, engineers can rapidly transfer and synchronise models, and it is possible to carry out complex analyses and design of metal and reinforced concrete (RC) structures.

The new version of LIRA-SAPR 2024 software provides extended functionality for two-way integration with Autodesk Revit. For engineers and architects, a lot of things have been significantly improved.
