Import of files from Bentley ISM, Ansys Apdl, and Scia Engineer. Merging one member with existing member. Intersections of solids using Boolean operators. Modelling of solids by extruding surfaces with relation to plane or point (with tapered sides as well). Filter in cross-section and material libraries including favourites. Input option for hybrid timber cross-sections. Orthotropic properties for quadrangle and membrane surfaces, as well as solids. Diagrams and extended criteria for nonlinear nodal supports and hinges. Member eccentricities from cross-section dimensions. Graphical user interface supporting the languages Chinese, French, Italian, Dutch, Polish, Portuguese, Russian, and Spanish. RFEM includes the following features amongst many others: The program version RFEM provides a wide range of useful features and options for efficient and user-friendly work on your structural analysis projects. This program forms the basis of a modular software system: RFEM determines internal forces, deformations, and support reactions of general plate structures with or without member and solid elements. 
The structural FEA software RFEM for analysis and design of plates, walls, shells, solids, and frame structures is a powerful program for various tasks in modern civil and structural engineering.
