Delete Structural Data
The cursor will change to a cross. If you click a disc or a lineation in the data display, it will be deleted. Discs and lineations you click on will be deleted until the Delete tool is inactive. To deactivate the Delete tool, click the icon to toggle it off.
If you have accidentally deleted an element from the display, the standard Undo (CTRL + Z) feature can be applied.
You can add discs and lineations to the data using the methods outlined in Add Discs and Add Lineations.
