Add Lines from New Lines Layer
The workflow to add line or a polyline is identical except for the number of vertices used to construct the feature geometry. A line feature has two vertices and a polyline has multiple vertices.
Description
Creating a line feature on a map helps distinguish the feature of focus and draws visual attention to a feature such as a fence or boundary. This workflow teaches how to add lines to a map, use the edit pane, and how to edit fields.
