Grant Boundary Adjustment

This command applies a Grant Boundary Adjustment by rotating and scaling a polyline. Before running this command, the grid projection must be set in Drawing Setup and a polyline must be drawn.

The Grant Boundary method is used to set lost corners on perimeters within public lands. Distances between the record and measured are compared to define a ratio for adjustments. A rotation is defined by the difference between the record and measured bearings to preserve the angular relationship at the lost corners and to adjust the distance at the same ratio through each lost corner.

Rotation: 8'42" Scale: 1.004612115
