In general an edge is created where one surface meets another. An edge could be a surface level edge, a kerb, a retaining wall, steps or terrace. Edges are often created using the Loft compound object instead of a simple extrusion to take advantage of the loft mapping parameters. The Loft mapping parameters enable kerb or brick materials to follow the curves of an edge as they do in the real world
In this example a kerb is created using Key 3D Edge Path and Key 3D Edge Section

Select Surface_B_Road again and move the surface down on the Z axis -0.15
NOTE: Placing all sections for lofts or other shapes for bevel profiles etc at the top left of the site, away from the site geometry, is a good habit. Sections and profiles are then available in an easy to access place for re-use at any time
TIP: Naming in this way ensures that any lofts are easily identified in the scene. When materials have been properly mapped to the kerb (later) it can then be renamed and converted to an editable mesh. This procedure ensures objects uses less system resources when creation, modification and material application has been completed
TIP: Always approach the creation of lofts in this way ie keeping a tight hold over the number of faces. Measures to reduce the amount of faces should be taken before loft creation when determining the amount of vertices on the splines used to create the landfom terrain. However, the shape and path sub-objects of the loft can be accessed on the Modify Panel after creation and number of vertices reduced if required
NOTE: To change other parameters on the loft such as the orientation (the loft sometimes is inverted) or the position of the loft on the path Ref: Key Fundamentals / Working with Objects
