Tekla Structures calculates bolt length using material thickness. To avoid having several bolt lengths where material thickness only differs slightly, set this advanced option to a positive or negative value. This value is multiplied by two and the result is subtracted from the material thickness in bolt length calculation. Enter the value in millimeters (all environments). Typical values are 0.001–0.5. The default value is 0.001.
This advanced option is model specific and the setting is saved in the options databasedatabase file that contains the settings of model-specific general settings and advanced options
There are two options databases, the model options database (options_model.db) and the drawing options database (options_drawings.db).
