Question:
How can I rotate a single foundation in RF‑/FOUNDATION Pro?
Answer:
A single foundation is rotated by rotating the nodal support in RFEM/RSTAB:
Open the "Edit Nodal Support" dialog box → select "User-defined axis system: Rotated" → click the [Edit] button.
Open the "Edit User-Defined Axis System" dialog box → set support rotation as you want (see Image 01).
Recalculate in RF‑/FOUNDATION Pro and display graphic (see Image 02).
