The Reshape tool is used to reshape multipoint, line, or polygon features by adding or removing geometry. Feature attributes are preserved.
Reshape a feature
To reshape a feature, complete the following steps:
- Follow the steps to select a feature.
- On the editing toolbar, click Reshape
.
The tools for reshaping features appear on the editing toolbar.
- Expand the Reshape menu
and choose Reshape
, Append
, or Subtract
to change the reshape method if necessary.
- On the editing toolbar, select a drawing tool. Drawing tools include Line
(default), Right angle
, and Freehand
.
- Draw a shape to add or subtract from the feature.
The shape must intersect the feature to add or subtract from it. To subtract from the feature, begin drawing the shape outside the feature.
- To finish reshaping 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.
If you are subtracting a shape from a feature, the area of the shape that intersects with the feature will be removed. If you are appending a shape to a feature, the area of the shape that does not intersect with the feature will be added.
- If the final vertex has already been placed, click the Complete button
- Repeat steps 3 to 6 to further reshape the feature if necessary.
- On the editing toolbar, click Finished
.
Reshape options
The following reshape options are available:
- Reshape
—Add or remove geometry from a feature.
- Append
—Add geometry to a feature.
- Subtract
—Remove geometry from a feature.
Reshape
Reshape adds and subtracts geometry from lines and polygons. The Reshape option draws lines, regardless of the feature type. The drawn line must intersect a feature when you use the Reshape option. In other words, Reshape cannot be used to create multipart features.
For line features, geometry is added after the drawn line intersects the line feature. If the drawn line intersects the line feature a second time, the segment between the two intersection points is removed.

For polygon features, geometry is added when the drawn line starts inside the polygon and passes through two edges to return inside the polygon. Geometry is removed when the drawn line starts outside the polygon and passes through two edges to return outside the polygon. If the drawn line intersects the polygon edge three or more times, geometry is both added and removed.

Append
Append adds geometry to multipoint, line, and polygon features. The Append option draws points, lines, or polygons depending on the type of feature.
For multipoint features, geometry is added at individual points.

For line features, geometry is added where the line is drawn. If the drawn line does not intersect the existing feature, a multipart feature is created.

For polygon features, geometry is added where the polygon is drawn. If the polygon does not intersect the existing feature, a multipart feature is created.

Subtract
Subtract removes geometry from multipoint, line, and polygon features. The Subtract option draws polygons, regardless of the feature type.
For multipoint features, geometry is removed by drawing a polygon around the points.

For line features, geometry is removed by drawing a polygon that overlays the line feature.

For polygon features, geometry is removed by drawing a polygon that overlays the polygon feature. You can use the subtract option to create a hole in a polygon feature.
