In this exercise, you will draw tangent segments between two existing PIs, a point specified by northing/easting coordinates, and a station block to define a bridge abutment alignment crossing the main roadway alignment.

1. On the View menu, click Named Views to display the View dialog box. Under Name, select 2, click Set Current, and then click OK.

2. On the Lines/Curves menu, click Line, enter .P (dot P) to use the Point filter, and then enter 1 for the Point number of the starting point.

3. Enter 2 for the Point number of the next point.

4. Enter .N (dot N) to use the Northing/Easting filter, and then enter 5018657.3345 for the Northing value and 273727.9099 for the Easting value for the next point.

5. Enter .N to toggle off the Northing/Easting filter, and then use an Insertion Osnap to select the station block on the north side of the main road for the ending point.

6. Press ENTER twice.

You now have three tangent segments for the bridge abutment alignment.
