What to do
Adding a placeholder to an existing boundary

- The mark linking panel will open.
- Select Add a placeholder from the bottom of the panel.
- Select Add a placeholder from the bottom of the panel.
- As you move your cursor over spatial view, you will see a message in a green box attached to your cursor telling you to Drop a placeholder on an underlying line.
- Left click the position in spatial view for the placeholder. When the desired location is selected, the placeholder will display as a solid red circle.
- Once you’ve finished adding placeholders, select Return to mark linking, at the bottom of the Add a placeholder panel, or select the Esc key to return to the Mark linking panel.
- A captured mark can now be linked to this placeholder, just like linking to an existing mark already in Landonline. See Linking marks using the spatial view for more information.
Adding a placeholder where there is no existing boundary
- To add a placeholder where there is no existing boundary, start the mark linking functionality, select Add a placeholder and then left click the Turn off the underlying lines layer label.
- Left click the position in the Spatial View for the placeholder. The placeholder displays as a solid red circle.

Deleting a placeholder
- On the spatial view, right click on the red placeholder symbol to select the placeholder. This will bring up the context menu.
- Left click on Delete placeholder.
- You will momentarily see a pop-up message telling you the placeholder has been successfully deleted.
When you add a placeholder to an existing line, which is in close proximity to another line, make sure you add the placeholder to the correct line.
