Transformation (width and height) of a curve at pass on 2 rails

Hi, everybody!
Whether there is some opportunity to edit transformation of a basic curve at pass on 2 rails (Sweep 2 Rails)? The curve (or curves) changes on width and height concerning rails, and it is possible to make somehow change only on width? It in general can be controlled?

Checking the “Maintain Height” option should do what you want. --Mitch


Thank you very much! :grinning:
