The Split tool is used to divide a multipoint, line, or polygon feature to create two separate features.
Split a feature
To split a feature, complete the following steps:
- Follow the steps to select a feature.
- To enable the Split tool, do one of the following:
- On the editing toolbar, click Split
.
- Use the Alt+T shortcut for Windows or the Option+T shortcut for Mac.
The tools for splitting features appear on the editing toolbar.
- On the editing toolbar, click Split
- Expand the Type of split menu
and choose Split by line
, Split by polygon
, or Split
(available for line features only) to change the split method if necessary.
- On the editing toolbar, select a drawing tool. Drawing tools include Line
(default), Right angle
, and Freehand
.
- Draw a shape or place a point where you want to split the feature.
The shape or point must intersect the feature to split it. If a polygon is split by a line, the split line must pass through two or more edges.
To split multipart features, use Split by polygon and draw the polygon around the part of the feature you want to split from the other parts.
- To finish splitting a feature, do one of the following:
- If the final vertex has already been placed, click the Complete button
on the editing toolbar to apply the changes. To discard the changes without creating the feature, click the Cancel button
.
- Double-click the map to add the final vertex and apply the changes.
The feature is split into two or more features.
- If the final vertex has already been placed, click the Complete button
- Repeat steps 3 to 6 to create additional splits in the selected feature if necessary.
- On the editing toolbar, click Finished
.
Type of split
The following three types of splits are available:
- Split
—Splits the feature at a single point. This option is available for splitting lines, including multipart features.
- Split by line
—Splits the feature using an overlapping line. This option is available for splitting lines and polygons, including multipart features.
- Split by polygon
—Splits the feature using an overlapping polygon. This option is available for splitting lines, polygons, and multipart features, including multipoints.
Split
Split divides a line feature at a single point.

Split by line
Split by line divides a line or polygon using an overlapping line.
For line features, Split by line can be used to split a line segment at multiple intersections.

For polygon features, Split by line can be used to divide the polygon. The line must intersect two or more edges.

Split by polygon
Split by polygon divides features using an overlapping polygon. Split by polygon is most useful for splitting multipart features.
The polygon should be drawn around the feature or features being split from the rest of the multipart feature.

Troubleshooting
If the split features disappear after they're created, it may mean a definition expression or filter is applied to the layer. Update or remove the definition expression or filter for the layer in Map Viewer to verify the features were split correctly.
