Use the Design menu > Slab Design Overwrites command to overwrite design parameters for a selected design strip(s) or slab object(s). A sub-menu consisting of Strip Based or Finite Element Based will display. If only one of these sub-commands is available, only design strips (Strip Based) or slab objects (Finite Element Based) have been selected.
The Design menu > Slab Design Overwrites > Strip Based command will access the Strip Based Slab Design Overwrites form.
The Design menu > Slab Design Overwrites > Finite Element Based command will access the Finite Element Based Slab Design Overwrites form.
Note: Design strip information can be accessed by expanding the Design Strip Objects sub-node on the Objects node on the Model tab of the Model Explorer window.
