The "best practice" approach to use the Bridge Modeler is to develop the model by using the parametric definition of the Bridge Object via commands in the "BrIMBridge" menu. If additional flexibility is needed, you can always use "BrIM > Bridge> Update Linked Bridge Model" menu command to "Convert to Unlinked Model" and make additional changes manually. By doing so, you are however loosing the advantage of parametric definition for modifying the model and for reviewing the results. Therefore, it is recommended to use this approach only when the model is fully finalized. In addition, it is also recommended to create a copy of the file before converting to unlinked model, such that you can always go back if changes to the parametric bridge definition are needed.
