Bracket parts are created in the Structural Detailing task. They are stored in the catalog database and selected during placement. When you place a bracket part, open the Properties dialog box to alter the rules selection.
Bracket parts are Smart Occurrences, so the catalog database points to the two-dimensional symbol for the bracket part as well as the Visual Basic rules.
Bracket part symbols define the shape of the bracket. The inputs to the symbol include the model geometry and parameter data. The output is a 2D curve adjusted to the model geometry and parameter data. By default, the bracket symbol files are delivered to the [Reference Data Folder]\CatalogData\Symbols\Brackets folder. Bracket part symbols are very similar to the symbols for bracket systems.
The Visual Basic rules for bracket parts choose a bracket based on the number of supports selected in the command.
The bracket part reference data is delivered by default to the SRDBracket.xls file in the [Product Folder]\StructDetail\Data\BulkloadFiles folder. Each worksheet in this file creates a Smart Class. Each row creates a Smart Item.
