Hello,
we often repair exsisting railway geometry, and usually have two alignments - existing and proposed.
The main data needed to contractor - horisontal/vertical correction values on every N-th station.
Unfortunely I can't find how simple to do such report/graphical representation of difference correction values in C3D.
It will be nice, if we have existing and proposed alignments logically connected, and result
of this connection (as horisontal/vertical difference) we see in separate view, like Profile View. If we change one of
alignments - we immediately see changes in our "difference" view.
Also better even if we have possibility add difference data graphically into Profile View bands.
I realized this idea writing couple pages of .NET code, genetating new profile view with hotisontal correction data.
Till now it have no dynamic connection.
