The StructSlabGeneral.xls workbook defines the slabs that you want to add to your catalog and hence to your model. When creating your slabs, there are custom attributes and required attributes. You can add your custom attributes using the Custom Interfaces Sheet sheet (described in the Reference Data Guide.)
Before defining slabs in this workbook, you must define the layers that you plan to use to compose your slabs in the StructSlabLayer.xls workbook. For more information, see StructSlabLayer Workbook.
After defining your layers, you define the compositions of your slabs in the Slab Composition Type sheet of this workbook. When the compositions are defined, you can then define your slabs in the Slab General Type sheet of this workbook.
