With this option an axis/a plane of the Global or the User-defined (UCS) co-ordinate system can be set for the required direction (e.g. the local y’ axis of a beam profile). The direction can be chosen from the drop-down list attached to the Predefined direction option. The available directions depend on the applied FEM-Design Module (e.g. Plate, 3D Structure etc.).

At supports, additional direction setting can be chosen from the definition tool palette:

1584716311818-707.png “Positive direction”:           The orientation is the same with the selected axis orientation;

1584716321509-100.png “Negative direction”:        The orientation is the opposite of the selected axis orientation.
