How can I create a catenary arch (chain line, kettenlinie) in RFEM 6? I have found the link below, but it seems it is not valid for RFEM 6?

Thank you very much for your request! 
The generators for creating various structurs are now managed as blocks within the Block Manager .
You can find a detailed guide on our Dlubal website explaining where to locate the Block Manager and how it works:

In the category “Blocks-Beams-Others” , you will find Block No. 003708 , which allows you to generate an arch.
A double-click on the preview image inserts the block directly into your model, as shown below:
If you have any further questions, feel free to ask — we’re happy to help!
Best regards
