Feature Line Move

When editing feature line elevations, the best practice is to use the grading feature line tools, such as the Elevation Editor, which provides reliable controls for incrementally raising or lowering an entire line or specified points. AutoCAD commands, such as MOVE and OSNAP, can give undesirable results unless used carefully. For example, an accidental OSNAP to an object at elevation 0 will set the elevation to 0. However, you can use the AutoCAD MOVE command to move a feature line horizontally.
