The instructions provided describe how to split line segments at midpoint. In this example, the workflow describes how to generate midpoints for a line feature dataset and split the lines at midpoints while retaining the attributes.
In ArcMap, right-click the line feature layer, and select Open Attribute Table.
In the attribute table, ensure that each segment is a single line feature. Proceed to Step 3 if the line dataset is a singlepart feature. Otherwise, run the Multipart To Singlepart tool to create a new line dataset that has each line segment as a single feature, as shown in the example below.
