Changing the Global Coordinate System Subsequently
Tips & Tricks
Before creating a structural model, every user is giving thoughts to the boundary parameters of the system and how to best represent the model. Special attention should be paid to the orientation of the global coordinate system. In engineering, the global Z‑axis is usually orientated downwards (in the direction of the self‑weight), while it tends to be upwards in architecture. These differences can often lead to complications during modeling, for example, when you replace global models or DXF layers.
In RFEM and RSTAB, it is therefore possible to subsequently change the orientation of the global axes. You can specify the according settings in the General Data of a model.
As a special note, however, it should be mentioned that the subsequent modification of these axes, especially with regard to the applied load (also orientation dependent), can very easily cause application errors, and therefore this function should be used only as an exception.

Depending on stiffness, mass, and damping, structures react differently to wind action.
- How is it possible to add or remove tables in the printout report?
- The display of result values is too inaccurate. Where can I set to see more result values for member internal forces?
- How do I apply prestress to tension members?
- I have numeric stiffnesses of my members. How can I assign the stiffnesses to a member without having to create a notional material and a cross-section?
- I have bought a new computer. How can I use my softlock license on it?
- How do I install the network license (USB dongle) on the server?
In my Dlubal Software programs, I have a problem that the umlauts and special characters cannot be displayed. How can I change that?
- Can I also use the load generator for the members that do not rest in one plane?
- How is the friction set on a member hinge via the COM interface?
- Is it possible to keep the results from RWIND Simulation when deleting the FE mesh if I only adjust materials or support conditions?
