XS_BOLT_LENGTH_EPSILON
Category in Advanced options dialog box: Modeling properties
Use this advanced option to round bolt length.
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 database.
