Hallo, i want to create a surface in the roadway modeler using an alternative surface option.But I want this surface to be perpendicular to the profile. For example the point for the alternative surface is at 1m distance from the vertical alignment, I want the alternative surface to be perpendicular to the profile at one meter elevation. As a result the elevation at that a particular station will be little more taking into consideration the vertical slope. Is it possible to do that in the road way modeler or is there any other function. Thank you for your help.
