I am having to change some geometry and beams deck, spacing Pedal stools and so on. I had already exported from OBM to Leap but need to update that Leap model to reflect the new changes done in the geometry. How do I Update that Leap File without having to input everything as far as loads, beam strand patterns criteria and so on.
If you are working in standalone OpenBridge Modeler (OBM) or in OpenBridge Designer (OBD) Standalone mode when you interop the model to analytics a new file gets created. There is no option to update the existing analytical file. But if you are working in OBD BIM Workflow you have an option to "Update Analytics"

If you are working in standalone mode I suggest you save the strand pattern so that you can load them in the new file:
