Layer Name

Select a drawing layer for the road layout to be displayed in.

Generate As

Select if the road must be designed using cross-sections or road strings. The cross-section method is slightly faster for long roads, while the road strings method is better for roads with complex edges, intersections and turning circles. The preferred method is road strings, while the cross-section method is included for legacy purposes for use with old existing designs.

However, you may change an existing design using the cross-section method simply by changing the method to Strings.
