Process 2, HSC mode 2

In the HSC mode 2, Akima spline curves are generated which lead through the specified corner points. At the start of prismatic segments, spline generation is cancelled automatically, and a tangential transition is realized. In the case of linear blocks, for example, prismatic segments are recognized via the knee angle and the block length change referred to an average block length.

Transition polynomials are inserted automatically (see HSC mode 1) in the case of block transitions in the prismatic range.
