After the contour of the ground has been defined, further landscape features can be incorporated. The features available here are flower beds, ways, terraces and water features. The appropriate means of entering the feature are also provided, so that for instance, a path can be inserted as a polygon or as a spline, whereas a flower bed can only be inserted as a closed polygon. Landscape features are created as surfaces, which automatically conform to the contours of the ground and the defined landscape forms. Since landscape features are discrete surfaces, they have their own materials, and can, as opposed to the terrain as a whole, be allocated textures from the catalog.
