I propose to add the possibility of dividing corridors with the retention of all attributes and elements such as point controls, feature definitions, keystations, etc. It can be seen in the programme files that such an intention to introduce a feature was there but its key sation never made it into the programme. A similar function is included in Autodesk Civil and works very well, it is a pity that in ORD such an important and necessary function has been omitted.
