I n this chapter, we will enter curve-fitted lines, point-to-point lines, parallel lines, and squared lines. Curve-fitted lines are defined at input by a small number of points, and the GIS will generate a smooth curve over these points to create the eventual line. They are suitable for smooth lines such as highways. Point-to-point lines are angular lines such as parcel boundaries. The operator must enter every one of its points. Parallel lines are generated at a distance from existing lines. Squared lines turn at 90† angles and are suitable for building outlines.

Add a curve-fitted line.
The demonstration Edit graphic data: adding a three-point curve in Demo 2 shows how to add a curve using three points. Show the points on the curve-fitted line. Use a command we have introduced before to show the points making up the curved line we have just created.
