YAPP Helps Define Your Surfaces
Besides creating perspective views and detailed interchange layout design as shown in the precious examples YAPP offers many more means and possibilities in defining and creating your surfaces. You can define layers of surfaces and assign elevations (profiles) to any curve on them by means of layer and multi-route capabilities built into YAPP. You can also make use of super elevation curves or any other carrying method of your own definition to create these profiles. Then you can smooth them properly, instantly redefining your surface in this way. This is much more than the classical route-interchange design by the well known plan-profile method. By this way, you can create very detailed elevation plans of surfaces such as sub-base, base and/or pavements as well as earthworks ready to be fed to construction. Following drawing shows such an interchange pavement plan on the Northern Costal Highway which is presently under construction.
