Trim or extend an unfinished line

Change Length Trim to Length trims or extends the length of an unfinished polyline sketch. A value greater than its current length extends the line. A value less than its current length trims the line. The tool is available on the context menu when you create a polyline feature.

The direction of the edit is determined by a positive or a negative value. A positive value preserves the first vertex and a negative value preserves the last vertex.

When you create a z-enabled polyline, the new vertex is assigned an interpolated z-value and the angular pitch of the line is preserved.

For steps to use this tool as you edit vertices, see Trim or extend a polyline feature.

    The Create Features pane appears.

  2. Click a polyline feature template.

    The template displays a tool palette, runs the default construction tool, and the construction toolbar appears at the bottom of the map.
