Within the field of cutting or packing of irregular shaped objects, $\Phi$-functions for pairs of objects have been proven to be useful tools in modelling as well as algorithmic aspects. In addition to \cite{pre4} further situations will be analysed how to construct $\Phi$-functions for pairs of complex objects by means of $\Phi$-functions for pairs of primary objects. Especially circular segments which result as intersection of a circle and a half-plane, are considered.
