3D Structural & BIM Software

3D Planning According to BIM

Structural analysis programs by Dlubal Software integrate seamlessly into the planning according to the method of Building Information Modeling (BIM).

The large number of interfaces ensure the data exchange of digital building models with RFEM or RSTAB.

DXF Interface

The DXF file format is the most commonly used exchange program in computer-aided design (CAD). The following overview shows the exchange options using DXF, which are applicable for RFEM/RSTAB.

Import

Lines can be imported as lines (RFEM) or as members. The names of layers are transferred as cross-section descriptions and the first material is assigned from the predefined materials. However, if the program recognizes a material or cross-section listed in the Dlubal database according to the layer name, these will be transferred as well.
Export

Members are exported from RFEM/RSTAB as lines. The line layers include information concerning the cross-sections and materials used in the program. In addition to the entire model including FE mesh, it is possible to export the numbering managed by the navigator.
Isolines

Another exchange option is to transfer the RFEM/RSTAB results as isolines in a DXF file. For this, you can directly select various elements such as isolines, FE mesh, values, and more.

Transfer of Reinforcement from RFEM/RSTAB (Top) to Revit (Bottom)

Bar Reinforcement Export to Revit

The reinforcement concept from RF-/CONCRETE Members can be exported to Revit. Rectangular and circular cross-sections are possible at the moment. The reinforcement bars can be modified afterwards in Revit.

Frequently Asked Questions (FAQs)

I would like to export a result using isolines or isosurfaces and load them later again. Is that possible?

I would like to read the reinforcement results (A _{s, -z (top)} , A _{s, + z (below)} , a _{sw, V, bracket} ) for a support from my RFEM or RSTAB file and read it into AutoCAD. With the dialog "Export" -> "DXF" I can only read the geometry. Is there a possibility?
