Creating a curve through endpoints (Endpoint Arc)

Endpoint Arc Endpoint Arc Segment 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, then drag the curve or press the R key to set the radius value.

Steps:
  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 Line.

    To create a vertex in a polygon

    Click a polygon feature template in the Create Features window and click the Polygon tool Polygon.

  2. Click Endpoint Arc Endpoint Arc Segment on the Editor toolbar construction method palette.
  3. Click the start point of the arc, then click the endpoint of the arc.
  4. Move the pointer to get the approximate radius for the curve.
  5. Click once to establish the endpoint of the arc.
  6. Press the R key and type the radius for the curve. You can also click again on the map to set the radius.
