Grading Optimization is a new service incorporated with Civil 3D and included with the Autodesk AEC collection. Grading Optimization gives the designer the ability to create dynamic, multi-layered grading calculations for an entire site at once. Using new intelligent grading objects and criteria, site grading calculations which used to take days can be accomplished in hours. Grading Optimization lets the user minimize earthwork costs and achieve the best possible grading solution by leveraging the power of automated iterative design.
