Segment construction tools

Segment construction tools create contiguous linear and curvilinear segments. They are available on the construction toolbar when a polyline or polygon construction tool is active. The toolbar is also available above the context menu when you right-click a map.

Tool	Description
Line	Create straight line segments between vertices by clicking or typing the vertex locations.
Right Angle Line	Create straight line segments at 90-degree angles between vertices by clicking or typing the vertex locations.
Arc Segment	Create circular arc segments by clicking or typing the location for a start point, a point through which the arc passes that defines the radius, and an endpoint. To specify a numeric radius value, press R.
Endpoint Arc Segment	Create circular arc segments by clicking or typing the location for a start point, an endpoint, and a point through which the arc passes that defines the radius.
Tangent Curve Segment	Create circular arc segments that are tangent to the previous segment using two points.
Bezier Curve Segment	Create nonlinear Bézier curved segments using control points and handles to shape the angle and height of the curve.
Trace	Create segments that follow another feature by using the pointer to trace the boundary of the feature.
Stream	Create free-form segments by streaming vertices with the pointer. Press O to check the Smooth setting and convert the segments to Bézier curves when you finish the feature.
