Creating a curve through endpoints (Endpoint Arc)

Endpoint Arc allows you to specify the start and endpoints of the curve, then define a radius for the curve. This is particularly useful in sketching culs-de-sac, where the beginning and ending points of the arc, as well as the radius of the cul-de-sac, are known.

To use Endpoint Arc, click to place the start point, click again to construct the endpoint, and then move the pointer. To specify a radius, click the map or press R and type the radius value.

1. These steps can be used to create vertices in either lines or polygons:

   To create a vertex in a line	Click a line feature template in the Create Features window and click the Line tool .
   To create a vertex in a polygon	Click a polygon feature template in the Create Features window and click the Polygon tool .

2. Click Endpoint Arc on the Editor toolbar construction method palette.
3. Click the start point of the arc.
4. Click the endpoint of the arc.
5. Move the pointer to show the approximate radius for the curve.
6. Specify the radius using one of the following methods:
   • Click the map.
   • Press the R key and type the radius for the curve.
