In the Modify Features pane, Explode separates the component parts of a multipart feature into single-part features and copies the multipart attribute values to each feature. You can discard the original multipart feature or choose to keep it and create the new features as component parts, each containing their own attribute values.
If you keep the original multipart feature, you can use the Selection Chip to select a component part and view or edit its attribute values. For steps to create new features as component parts to an existing feature using feature construction tools, see Continue feature.
To explode a multipart feature, click Explode , select the feature, and click Explode. To create the new features as component parts, check Keep original feature after explode.
