The direct interface with Revit allows you to update the Revit model according to the changes you have made in RFEM or RSTAB. Depending on the modification, the Revit objects may have to be regenerated (deleting the object and subsequent regeneration). The regeneration is performed on the basis of the RFEM/RSTAB model.
If you want to avoid this regeneration, activate the check box 'Update only materials, thicknesses, and sections'. In this case, only the properties of the objects will be adjusted. Changes different from those in material, surface thickness, and section are, however, not considered in this case.
The number of degrees of freedom in a node is no longer a global calculation parameter in RFEM (6 degrees of freedom for each mesh node in 3D models, 7 degrees of freedom for the warping torsion analysis). Thus, each node is generally considered with a different number of degrees of freedom, which leads to a variable number of equations in the calculation.
This modification speeds up the calculation, especially for models where a significant reduction of the system could be achieved (for example, trusses and membrane structures).
Time-dependent concrete properties, such as creep and shrinkage, are very important for your calculation. You can define them directly for the material in the structural analysis program. In the input dialog box, the time course of the creep or shrinkage function is displayed to you graphically. You can easily select the modification of the applied concrete age, for example, due to a temperature treatment.
Graphical display of the connection geometry that is updated in parallel with the input
The Steel Joints Template included in the add-on allows you to select from several connection types and, and once selected, it will be applied to your model.
Wide range of cross-section shapes: Includes I-sections, channel sections, angles, T-sections, built-up cross-sections, RHS (rectangular hollow sections), and thin-walled sections
The Template covers connections from three general categories: Rigid, Pinned, Truss
Automatic adaptation of the connection geometry, even if the structural components are subsequently edited, based on the relative relation of the components
Results are displayed in result tables sorted by required designs. Clear arrangement of the results allows for easy orientation and evaluation.

All data are documented in a clearly arranged printout report, including graphics. In case of any modification, the printout report is updated automatically. COMPOSITE-BEAM is a stand-alone program and does not require the RSTAB license.
There are various options available for modeling a roof. Graphical representations facilitate the geometry input. Modifications are updated automatically.
In addition, it is possible to consider cross‑section weakening on supports. Optionally, you can define if the design of support pressure on the rafter side should be performed.
Permanent loads (for example, roof structure) can be entered using the comprehensive and extensible material library. Loads due to cantilevers and collars/ties can be entered separately. Generators integrated in RX-TIMBER Purlin allow for convenient generation of various wind and snow load cases. You can manually add any concentrated and distributed loads.
Load cases are displayed graphically and superimposed in automatically generated load combinations according to EC 5. For stability and serviceability limit state designs, you can change the data manually, for example, for example, for cantilevers (roof overhang), it is necessary to ignore the SLS.

Foundation and bucket dimensions can be user-defined or determined by the module. You can edit the determined reinforcement manually. In this case, the designs are updated automatically.
