During the scanning process the 3D scanner may pick up additional artifacts and add them to your scan. Usually this is due to either lighting errors or the use of stands or props. You can edit these items out of your scan.
Since the scan is 3D, you can usually orient your scan to isolate the artifact by clicking and dragging the scan. Using the scroll button on the mouse will zoom in and out of the You want the artifact as isolated from the rest of the scan as possible. See the image below: a stand used to angle the shark jaw was partially picked up by the scanner. The shark jaw has been rotated to isolate the stand.
Hold down the Shift key and left mouse button to select as much of the stand as you can. This will select any data within the loop you have created. If you haven't managed to isolate the image artifacts, it will also select a part of your scan that you wish to keep, so be cautious.
Once you have managed to select the data, it will be highlighted in red. Rotate the object to ensure you've not selected a part of the scan you wish to keep.
If you have accidentally selected a portion of the scan, you may use the Control+Left Mouse to deselect a portion. Alternatively you may hit the "Deselect" button in the Edit Tools toolbar to deselect everything.
In some cases it may be easiest to select a small portion of the scan and press the "Revert" button in the Edit Tools toolbar. This reverses the selection, selecting everything but the part you just highlighted.
When you are satisfied with your selection, press the "Delete" button in the Edit Tools toolbar to erase the artifact.
If you deleted something you didn't intend, press the "Undo" button in the Edit Tools toolbar to undo the erasure.
