Autodesk Grading Optimization is an interactive tool that facilitates grading various land areas such as sites, road interchanges, and around structures. It consists of optimization algorithms that work toward surface smoothness while accommodating user imposed constraints. These design constraints include grading and drainage elements. The constraints are entered as global parameters and as individual grading element parameters. Once optimization begins, the real-time problem solving can be observed. Using several visualization themes for the surface, or by watching the trends of the convergence plots, you can stop and change designs or let it run until a desired grading solution is found. If a solution is not possible, a best approximation is provided within your constraint requirements.
