Slab Drainage Settings

Slab drainage settings for the selected slab are set before the drainage elements are added, in the Slab Drainage Settings dialog box; access it by clicking the Slab Drainage tool from the Building Shell tool set and then clicking Settings from the Tool bar. These settings serve as the new defaults for drainage elements added to the slab until the settings are changed.

Some, but not all, of the settings for individual drainage elements can be edited after placement with the Edit mode of the Slab Drainage tool (see Editing Slab Drainage Elements).
