Polyline and polygon construction tools

In the Create Features pane, feature construction tools for polyline and polygon layers create features using the pointer. Segment construction tools for the active tool are available on the construction toolbar in the map view and above the context menu when you right-click the map.

When you use polyline and polygon construction tools, consider the following:

• To apply a specific geometric constraint, right-click an existing feature.
• To type a numeric value for direction, distance, or elevation, right-click the map.

Polygon feature tools

Polygon feature construction tools are described in the following table:

Tool	Description
Polygon	Create irregular polygon features. Feature geometry can comprise straight and curvilinear segments using the segment tools that appear on the construction toolbar.
Regular Polygon	Create equilateral polygon features at a specified center point with a specified circumscribed radial distance. The number of segments is a property of the tool.
Freehand	Create a free-form polygon with the pointer. When you finish the sketch, all segments are converted to Bézier curves.
AutoComplete Polygon	Create polygon features adjoined to existing polygon features on the same layer. Coincident segments are automatically generated along any traceable segments between the first and last vertices that are sketched across or touching existing polygon features.
AutoComplete Freehand Polygon	Create a free-form polygon with the pointer. When you finish the sketch, all segments are converted to Bézier curves.
Rectangle	Create planar rectangular or square features using the pointer or numeric values.
Circle	Create planar circular features using the pointer or numeric values to specify a center and a radius.
Three Point Circle	Create planar circular features using the pointer or numeric values to specify three points defining the circumference.
Ellipse	Create planar ellipse features using the pointer or numeric values.
Right Angle Polygon	Create geometry segments with straight line segments constrained to 90 degrees from each previous segment.
Trace	Create continuous segments that follow the geometry of other features on layers with snapping enabled.
Streaming	Create a free-form sketch by automatically creating vertices at constant intervals as you drag the pointer. This tool is available on the construction toolbar and context menu when you create a polyline or a polygon feature.

Polyline feature tools

Polyline feature construction tools are described in the following table:

Tool	Description
Line	Create polyline features comprising multiple straight and curvilinear segments.
Two-point Line	Create two-point line features. The feature is automatically finished when you create the second vertex.
Radial	Create a series of two-point line features that radiate from a common location.
Freehand	Create a free-form polyline feature that follows the pointer. Clicking the map a second time finishes the feature and automatically converts the segments to a series of Bézier curves.
Right Angle Polygon	Create straight segments constrained to 90 degrees from each previous segment.
Split	Create a polyline feature across an existing line feature on the same layer and split both lines where they intersect.
Rectangle	Create planar rectangular or square features using the pointer or numeric values.
Circle	Create planar circular features using the pointer or numeric values to specify a center and a radius.
Three Point Circle	Create planar circular features using the pointer or numeric values to specify three points defining the circumference.
Ellipse	Create planar ellipse features using the pointer or numeric values.
Trace	Create continuous segments that follow the geometry of other features on layers with snapping enabled.
Streaming	Create a free-form sketch by automatically creating vertices at constant intervals as you drag the pointer. This tool is available on the construction toolbar and context menu when you create a polyline or a polygon feature.
