TRUE to use the weld size as the leg length (z) of the fillet welds.
FALSE to use the weld size as the throat thickness (a) of the fillet welds.
The weld prefix overrides the setting of the advanced option XS_ISO_LEG_LENGTH_AS_WELDSIZE. If you have set the prefix of a weld to a , the weld size determines the design throat thickness. When the weld prefix is z , the weld size determines the leg length.
If the last character of the weld prefix is s , Tekla Structures creates the solid weld object so that a equals weld size.
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).
After changing this setting, modify existing welds or their properties to activate the new setting and to update the weld solids.
