When working with a finished surface model that includes a curb, operators often need to apply a horizontal offset to excavate beneath the curb from the road's edge. If the supplied model doesn’t cover all necessary areas, adding a consistent fall at the model's edge is often required to ensure proper rainwater drainage and prevent puddling. There are many more use cases for this feature. Skilled operator’s will combine the supplied model with infield adjustments to create more efficient workflows.
