The Recognize Substation object option should be set when exporting or importing model data with an ISM repository.

The option is found on the Transformation tab in the Export to ISM, Import from ISM, Update to ISM, and Update from ISM dialogs.

• OpenBridge Modeler detects if selected objects belong to a Substation frame such as: Truss, Symmetric A Frame, Vertical Frame, Single Frame, or Lightning Rod.
• If detected, OpenBridge Modeler automatically adds all substation frame components to target sets during the export or update processes. Otherwise, only the selected objects are exported or updated as OpenBridge Modeler objects, disregarding the Substation identity.
• OpenBridge Modeler also detects if the Substation frames are in the correct state. If the frames are in the "Physical Model" state, OpenBridge Modeler stops the export or update process and displays an alert: Cannot exchnage physical model when 'Recognize Substation object' is selected.
• During export, the axial behavior of Truss members is set to compression and tension. When updating to or from an ISM repository, Truss members always report to OpenBridge Modeler as compression and tension.
• Fix point supports are reported or added to the ISM repository for each Substation frame leg. Since support types cannot be changed in the OpenBridge Modeler model - similar to the axial behavior - they cannot be synchronized with the ISM repository.
• When the Recognize Substation object option is cleared, OpenBridge Modeler exports all selected objects without checking their model state and treats all as OpenBridge Modeler objects.
• Upon completing analytical work in STAAD.Pro, you must first update the ISM repository to synchronize any changes. Then, update from the ISM repository in OpenBridge Modeler to see the changes in the OpenBridge Modeler model.
