The company LEICHT was awarded the design phase for the Champagne Bar’s new roof located at the Goodwood Racecourse. The planning steps included the form-finding process, the membrane and supporting steel structure approval and design, and the membrane and cable cutting patterns.

With the activated option 'Topology on Form-Finding Form' in Project Navigator - Display, the model display is optimized based on the form-finding geometry. For example, the loads are displayed in relation to the deformed system.
Activating 'Show Form-Finding' in the shortcut menu leads to an automatic preliminary form-finding according to the saved form-finding properties when you change the structure of membrane surfaces. This interactive graphics mode is based on the force density method.
