In the DIN, EN and ISO datasheets (as well as other country standards) specific sizes are often recommended to be avoided.
Via the configuration file under $CADENAS_DATA/datasetup/avoid_parts.cfg (set for CADENAS’ standard parts and administratively expandable for customers) these sizes may be marked or hidden.
In the PARTdataManager in the parts view, the affected rows are identified by a symbol.
