DEAR ALL,
BEST
There is no single command to calculate the total weight of a building.
You could produce schedules of the various elements, the structure for example and post-process in Excel to aggregate a total structural weight.
Please refer to help topic Home > OpenBuildings Designer > DataGroup System > DataGroup Data Tools and Utilities > Schedules for more information.

Thank you very much for your answer, yes noted remark to follow up by DataGroup system, but it is better to design a command in the tools bar to quick calculation the total loads BLD that's advised the structure note for Pre-designed solutions of foundations types before export the files to STAAD or SAP or ETABS.
Best Regards
