How can you display the existing ground in Roadway Designer as dashed line instead of solid line?
While it is not possible to change the Line Style, Scale, or Weight for a surface line in Roadway Designer (only the color), there is an option that will allow you to view your design surface(s) as a dashed line. This is helpful when trying to differentiate between existing and design surface. From within Roadway Designer, go to Tools > Options and toggle on “Triangulated Surface”. With this option toggled on, the triangulated surface will be displayed as a red dashed line in the cross section view.
