In RFEM, the graphical results are smoothed on the basis of the results at the FE mesh points. The results are transferred to REVIT on the basis of the results on the grid points. In RFEM, the grid for the surfaces is set to 0.5 m by default. In this case, set a fine grid for the surfaces, and the graphical display of the results in RFEM and REVIT is comparable.
Different Surface Reinforcement Graphic in REVIT
When exporting the additional required surface reinforcement to REVIT, the graphic displayed in REVIT and RFEM does not match; how can I correct this?

The aim of this technical article is to perform a design according to the general design method of Eurocode 2, using the example of a slender reinforced concrete column.

Surface reinforcements defined in the RF-CONCRETE Surfaces add-on module can be exported to Revit as reinforcement objects via the direct interface. To do this, you can optionally select surface, rectangular, polygon, and circular reinforcement areas in RF-CONCRETE Surfaces. In addition to bar reinforcement, it is possible to export mesh reinforcement.

The "Nonlinear Material Behavior" add-on includes the Anistropic | Damage material model for concrete structural components. This material model allows you to consider concrete damage for members, surfaces, and solids.
You can define an individual stress-strain diagram via a table, use the parametric input to generate the stress-strain diagram, or use the predefined parameters from the standards. Furthermore, it is possible to consider the tension stiffening effect.
For the reinforcement, both nonlinear material models "Isotropic | Plastic (Members)" and "Isotropic | Nonlinear Elastic (Members)" are available.
It is possible to consider the long-term effects due to creep and shrinkage using the "Static Analysis | Creep & Shrinkage (Linear)" analysis type that has been recently released. Creep is taken into account by stretching the stress-strain diagram of the concrete using the factor (1+phi), and shrinkage is taken into account as the pre-strain of the concrete. More detailed time step analyses are possible using the "Time-Dependent Analysis (TDA)" add-on.

In the Concrete Design add-on, you can determine the required longitudinal reinforcement for the direct crack width analysis (w k).

For the design of reinforced concrete members, there is the option to automatically determine the number or diameter of rebars.
I would like to export the reinforcement results (As,-z, As,+z, asw,V) of a beam from my RFEM 5 file and import them into AutoCAD. Using the "Export" → "DXF" dialog box, I can only read the geometry. Is there any option for this?
How can I check the determination of the required reinforcement?
