Frequently used materials and cross-sections can be summarized in favorite lists and allow faster selection during modeling. This video shows how to create a favorite group in the material and cross-section library.

Extensive cross‑section and material libraries facilitate the modeling of plate and beam structures. These databases can be filtered and expanded with user-defined entries. It is possible to import and analyze special cross‑sections from SHAPE‑THIN and SHAPE‑MASSIVE.
![Export RFEM or RSTAB Models to *.glb or *.glTF Format](/en/webimage/010965/2466101/N_386_03.png?mw=512&hash=148c1c16f3620b9ca170dc77253f6c2830d84b73)
RFEM and RSTAB models can be saved as 3D glTF models (*.glb and *.glTF formats). View the models in 3D in detail with a 3D viewer from Google or Babylon. Take your VR glasses, such as Oculus, to "walk" through the structure.
You can integrate the 3D glTF models into your own websites using JavaScript according to the instructions (as on the Dlubal website Models to Download): "Easily display interactive 3D models on the web & in AR" .
![Activation of Camera Flight Mode in RFEM](/en/webimage/007231/1773731/Kamera-Flugmodus.png?mw=512&hash=bfe40bd5994b64cf3b32c3ec1894bde55d8396b8)
With the Camera Fly Mode view option, you can fly through your RFEM and RSTAB structure. Control the direction and speed of the flight with your keyboard. Additionally, you can save the flight through your structure as a video.
!["Update only Materials, Thicknesses, and Cross-Sections" Export Option](/en/webimage/006849/1585500/eng-png.png?mw=512&hash=518d14ee46c7f75cf5f7af8b3e50b033198d7776)
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.
