Answer:
The trigger for this is the rotation of a member. A member rotation can be defined in RFEM and RSTAB using two options:
- Option 1: Rotation via Angle
- Option 2: Rotation via Help Node
These options can be specified in the detail settings for importing the .stp file. If the function shown in Image 02 is activated, the first option (by angle) is used. If you deactivate this function, a help node is automatically created with which the member rotation is defined.
