The described classification also provides unipolar representation in parallel besides the multipolar representation. The classification is analogously to the described cases.

Following figure is showing a coil in unipolar representation.

Unipolar representation

This is specified in the classification by the Representation type feature of the CNSCAX|GFX|SYMREP class. The mapping between 3D connections (CNS_CP|4|3 ) and 2D connections ( CNSCAX|GFX|1 ) can be omitted here. Compare Fig. „Data model symbol representation / layout“.
