Class system hide [Hide class system]: Class systems can be hidden. The settings for this are $CADENAS_DATA/datasetup/classsystem.cfg in the file . Hidden class systems are used in 3Dfindit and PARTdataManager is no longer available for selection.

If the classification system is hidden, it is also hidden in the partial information by default. This can be changed using the Show class system in part information checkbox.

Show class system in part information: See Section 5.12.18.2, “Parts information ”.

Classes can be hidden [Classes hideable]: With the two setting options Hide classes [Classes hideable] and Hide features [Attributes hideable], you can also hide individual elements. If these settings are active, an additional column with the checkbox for hiding is displayed in the features and in the dialog box Edit class... dialog box with another checkbox for hiding.

Linked variables that are hidden are $CADENAS_DATA/datasetup/classsystem/"class system name"/"class system name"_ml_"language".csv in the file .

Features can be hidden [Attributes hideable]: See above
