Introduction
The Point Cloud Editor (Multibeam Editor) is a tool for 3D editing of multibeam and pointcloud data. The editor works on all pointcloud data displayed in the 3D window. All editing of data is done by flagging, which means that all editing can be reverted later.
How to open the editor
The editor is opened from the Seafloor Main Menu. Click Edit and then click Point Cloud (Multibeam) Editor.
The editor can also be opened by right-clicking the Multibeam folder menu.
The editor can also be opened by clicking the Tools menu on top of Geocap.
The editor
The Point Cloud Editor dialog.
The editor consists of two button rows. The "Selection" buttons on top provides different methods to select which points you want to edit. The "Action" buttons at the bottom provides different actions for the selected points.

The action buttons
Button | Shortcut key | Description | Documentation |

| <ctrl>+'y' | redo | Redo the action or selection that you have previously undone with the undo button |
| <delete> | Delete | Flag the selected points as deleted. |
|

|
| set flag | Set userflag to selected points. |
 | remove flag | Remove flag from selected points. | |
 | Extract selected points | Extract the selcted points and save in the project. Browse to the project folder and save the points as a Poly Data. | |
|
| Edit selected | The selected points will become selectable. All other points are now not selectable. Use this to isolate the area you want to edit. When you perform further selections, points outside the edit area will not be selected by mistake. |
|
| Edit all | Will make all points selectable again. |
Only visible points are selected with the selection buttons. The "Point flag visibility filter" make some points invisible (by default the deleted poitns). These points will not be selected. You can modify the point flag visibility filter to control which points you want to select. Another similar option is to un-toggle (and hide) datasets in the project you want to ignore, when you do a selection.
