The R3D3-Rama 3D program is designed for construction engineers. It is used for static calculations and dimensioning of planar and spatial bar systems. Thanks to the convenient and clear user interface, the program can be used not only for design, but also for educational purposes.

      Data are intuitively entered in the program - the system geometry can be defined using only a mouse. The program works with CAD-type applications and the ArCADia-ARCHITECTURE system. Basic function generators are available. The program contains a library of rolled and cold-formed profiles, reinforced concrete and timber elements. The program can be used for easy insertion of planar and spatial bar systems, both small systems comprising a number of bars, and large 3D structures containing hundreds of bars and nodes. Therefore, it is possible to count such construction systems as: multi-level and multi-bay frames, planar and spatial trusses, lattice towers, surface bar structures, bar grates, etc. The program makes it possible to work with dimensioning modules according to Eurocodes: EuroStal, EuroŻelbet and EuroStopa.
