ROTATE |
Rotates the cross section an angle specified in VALUE (degrees). The rotation angle is counter clockwise, from Y axis towards Z axis. |
Notes
- When changing the shear or torsion reinforcement cover (REC), all the properties which depend on shear or torsion checking and design are automatically recalculated for concrete sections.
