Components of BIM technology
- New input tables have been added for setting/correcting data: dissipation coefficients, Rayleigh coefficients, an enhancing coefficient Fvk, and custom mosaic data.
- The creation of a single block of axes at the project level—with alignment to selected building floors—has been added, replacing the axes block on every floor as in previous program versions.
- Import of the IFC model into the configured project template has been implemented.
- When importing multiple buildings from IFC, the option to import them into separate buildings in LIRA-CAD has been added.

- The ability to import DWG floor plans into the current or a new project has been added.
- Automatic creation of openings along curved walls based on the DXF/DWG base for floor plans has been added.
- Display of the selected layer (instead of the List input name) in the “Layer Filter” node has been added.
- Improved recognition of the thickness of curved walls when constructing walls along the contour from the DXF/DWG base.
- Creation of openings along curved walls using the “Create windows at the intersection of walls and lines” node with the DXF/DWG base has been added.
- For the node “Advanced floor creation based on specified levels,” an option has been added to enable floor creation as in previous program versions (option “Upper floor levels – Yes”).
- Expanded functionality of the Blast node: an option has been added to account for or exclude the formation of a negative blast phase when constructing the graph of the explosive wave impulse’s effect (see blast analysis); for rear walls (those positioned at angles greater than 160° relative to the explosion epicenter), the gradual pressure increase caused by the shock wave’s flow along their back surface is taken into account.
