/** Create transformations

* is not counted.
*
* Depending on Mode selection list will be constructed differently:
* 1. For "Overall Length" each transformation will move the shape it is applied to by the distance
* (Length / (Occurrences - 1)) so that the transformations will cover the total Length.
* 2. For "Spacing" each transformation will move the shape by the distance explicitly given in
* the Offset parameter.
*
* If Direction contains a feature and a face name, then the transformation direction will be
* the normal of the given face, which must be planar. If it contains an edge name, then the
* transformation direction will be parallel to the given edge, which must be linear
*
* If Reversed is true, the direction of transformation will be opposite
