XS_USER_DEFINED_BOLT_SYMBOL_TABLE
Category in Advanced options dialog: Marking - bolts
This advanced option defines the file name of the user-defined bolt symbol table file. For example, enter bolt_symbol_table.txt.
You can optionally enter a full path to the bolt definition file if you want to use it from a specific fixed location. Without the path, Tekla Structures searches for the file in the model, firm, project, and system directories.
This advanced option is model specific and the setting is saved in the options database.
