Detailed Description

This tool is used for transferring parameters from 3d curve of the edge to pcurve and vice versa.

Default behaviour is to trsnafer parameters with help of linear transformation:

T2d = myShift + myScale * T3d where myScale = ( Last2d - First2d ) / ( Last3d - First3d ) myShift = First2d - First3d * myScale [First3d, Last3d] and [First2d, Last2d] are ranges of edge on curve and pcurve

This behaviour can be redefined in derived classes, for example, using projection.
