Information of parts already classified according to eCl@ss, can be mapped to the CNS classification. Otherwise 3D data in PARTsolutions (connection points classified as electrical connections) have to be equipped with additional information from data sheet.
CADENAS supports a certain subset of the connection properties ( Electrical Connection class) that are defined as part of eCl@ss ADVANCED. This set can be extended at any time if required.
The following illustration shows (framed in red) the currently available connection properties (Electrical Connection = CNS_CP|4|3 ) called up under PARTproject -> Extras menu -> Class systems: Edit. [Class systems: edit...].
Class system CNS -> Filter connection points [Connection points] -> Insertion Point -> Electrical -> Electrical Connection
The following figure shows the currently available connection properties (Electrical Connection = CNS_CP|4|3 ) called up under PARTproject -> Edit project -> General tab -> Characteristics (CNS)
The following listing exemplarily picks out some attributes and shows possible values:
Currently supported connection types (upgradeable on request)
You can set the type in the Class variables dialog.
You can also set the type in the Published elements dialog area.
