XS_MAX_MERGE_DISTANCE_IN_VERTICAL
Category in Advanced options dialog: Marking - parts
Use this advanced option to define the maximum vertical distance between the associativity points of the reinforcement marks within which identical reinforcement gets merged reinforcement marks. This advanced option only affects merging of reinforcing bar marks pointing to individual reinforcing bars, not marks pointing to a group of reinforcing bars, or marks within a group of reinforcing bars. The default value is 600 mm.
In the example below, the associativity points of the reinforcement marks are not within the defined distance (600 mm), so the marks will not be merged.

This advanced option is model specific and the setting is saved in the options database.
