- Edit your schematic dataset within Schematic Dataset Editor.
- If the schematic dataset resources are not arranged in a tree view in the Schematic Items window, click Views in the Schematic Dataset Editor toolbar and click Project Tree.
- Expand the External References main entry at the bottom of the Dataset Editor tree.
- Right-click the entry related to the external reference you want to remove in the Schematic Dataset Editor tree and then click
Delete.The entry related to the external reference and all the schematic attributes based on that removed external reference automatically disappear from the Schematic Dataset Editor tree.
