• New technology for generation of design models by text tables with data. This technology enables the user to transfer data to LIRA-SAPR from other software. One example is the update for parameters of elastic foundation by analysis results of the interaction 'overground structure-foundation-soil' from Midas GTS NX, PLAXIS, etc.
• Two-way converter 'Tekla Structures 2018і – LIRA-SAPR – Tekla Structures 2018і' is introduced. Converter 'Tekla Structures – LIRA-SAPR – Tekla Structures' enables the user to carry out complete analysis and design of steel and RC structures.

• Based on 3D soil model, design values of soil resistance are computed at level where imported loads are applied to or at the specified levels and then these values may be presented as mosaic plots. With this analysis the user could evaluate the bearing capacity of soil selected as the base for buildings and structures.

• When importing *.dxf files, the program automatically generates structural blocks from objects in AutoCAD layers.

• In main dialog boxes, like DCL, DCF, ranges of colour palette, etc., visual components are updated to edit tables with input data. Some issues with input data were fixed; they arised when previous editable tables were used in the latest versions of OS Windows.
