XS_REBAR_RECOGNITION_EXTRA_POINT_SHORTENING
Category in Advanced options dialog: Concrete detailing
Use this advanced option to set the default value for Extra point shortening that is used in rebar shape recognition and when reinforcing bars in rebar sets are generated.
Extra point shortening is used for defining whether two reinforcing bar legs ('1-2' and '2-3' in the image below) can be considered as one leg ('1-3').

Define the maximum allowed difference between the distances '1-3' and '1-2' + '2-3'.
The default value is 0.3 mm.
This advanced option is model specific and the setting is saved in the options database. Reopen the model to activate the new value.
If needed, you can override this setting by modifying rebar definitions in the rebar catalog (rebar_database.inp) or by using the Shape recognition user-defined attributes of individual reinforcement objects.
