Reshape a feature

The Reshape tool Reshape replaces existing segments of a line or polygon feature with newly sketched segments where your sketch crosses the feature. Existing attribute values for the original feature are preserved. This tool is available in the Modify Features pane.

Sketched z-aware vertices are assigned elevation values specified on the Edit tab, in the Elevation group. Existing feature elevation values are preserved.

Z-value assignment
The diagram shows how z-values are assigned to vertices.

To replace the entire feature, see Replace feature geometry.
