Advantages of the software

  • User-friendly and powerful tools for graphic generation and editing parametric 3D models provide the architect with much scope for creativity.

  • Parametrization and structuring of project components enable you to supervise even highly complex projects as it is easy enough to modify the model at any stage of design; it will produce great number of different project variants and encourage creative concept.

  • Familiar concepts and terminology, such as storey, floor slab, wall, column, beam, opening, staircase, sectional elevation, facade, etc., enable you to proceed to work without delay for studying additional concepts and terms.

  • As the program has option to obtain plans of storeys, sectional elevations and facades based on unified 3D model of structure, then all these views comply with each other and no user errors will occur.

  • Preparation of drawings as well as notations for dimensions, construction lines, elevation marks, radius, diameter, dashed lines are presented according to SPDS.

  • Accurate and adequate (with account of location of bearing layer in multi-layer structures) analythical model for generating FE model enables you to carry out strength analysis and evaluate structures in LIRA-SAPR program.

  • Flexible user interface enables you to adjust menus, shortcut keys, location of dialog boxes and appearance of the screen according to your own preferences.

  • Open architecture of the program, support for OLE interfaces and user-defined scripts provide you with great scope for program development, as program functionality may be added not only by developers but by qualified users as well.
  • Functionality of SAPFIR-3D software is expanded with wide diversity of features presented in SAPFIR-Structures and SAPFIR-RCstructures modules


    This module enables you to generate design model of building or structure based on 3D information model of building presented in SAPFIR-3D program. Design model generated in SAPFIR-Structures module will be transferred to LIRA-SAPR environment for further analysis and design. This version of SAPFIR-Structures enables you to generate and edit finite element meshes including plates and bars, and static loads as well. Initial model of the structure is generated with interactive graphical tools provided in SAPFIR-3D. Moreover, it is possible to import 3D and 2D models generated in other graphic environments, such as Allplan, Revit, AutoCAD, etc.


    This module enables you to design floor slabs and stiffness diaphragms. It is also possible to obtain working drawings for reinforcement, specification for reinforcement, list of steel consumption and list of components for every structural element. SAPFIR-RCstructures module will import analysis results for reinforcement from LIRA-SAPR software and display contour and mosaic plots for reinforcement as a background for the floor slab that is considered. Colour palette for presentation of analysis results may be adjusted; you could also define main reinforcement, in this case contour plots will be modified automatically. On the contour plot background you could arrange zones of additional reinforcement.
