Set this advanced option to TRUE to only display inches in weld length symbols. If you do not want to do this, set this advanced option to FALSE. This advanced option only works when the imperial units are in use. The default value is TRUE.
When you only display inches means that instead of showing 1ft 2inch it shows 14inch, for example.
This advanced option is user specific and the setting is saved in options.bin under user folder. Restart Tekla Structures to activate the new value.
