Terrain Sculptor Pro (TS Pro) is a utility to assist you in creating undulations in and otherwise making your Microsoft Flight Simulator and Lockheed Martin Prepar3D (collectively "FlightSim") terrain near your airport (or anywhere else) more representative of the real world. While other more-general-purpose tools, such as sBuilder and sBuilderX also do some of this, TS Pro's user interface is tailored for these specific functions and much of the "grunt-work" required by those other tools is done for you. Instead of requiring you to draw every sloped poly individually, TS Pro allows you to place a single node where the polys will intersect and to specify the elevation of this point. And, instead of hand-crafting individual blending triangles to mate with the existing mesh, Terrain Sculptor slews the user aircraft along a boundary you specify (with a few points), recording the mesh elevation and automatically creating these blend triangles for you.
But, that's not all. Terrain Sculptor Pro reads TDF, LWM and CVX terrain .bgls as well as .sbx files generated by sBuilder and sBuilder. Of course, you can also start terrain projects from scratch either by specifying a lat/lon position or identifying an airport .bgl. In the latter case, the project opens with an image of the airport in the background. TS Pro allows you to define and manipulate any valid FS9, FSX or P3D terrain element and compiles any set of terrain element for either FS9 or FSX, substituting equivalent terrrain elements as necessary.
