Classify Fence
Classify Fence tool classifies points inside a fence area.
The fence area can be defined by drawing a fence element before starting the tool.
The tool works in top views as well as in section views. The user can define settings for the temporary display of the help lines for the tool.
To classify points inside a fence:
1. Select the Classify Fence tool.
The Classify Fence dialog opens:
2. Define settings.
3. If a fence has been drawn, accept the fence contents with a data click inside the view.
This classifies the points inside the fence.
OR
3. Digitize a fence around the points you want to classify by placing data clicks inside a view. The fence is closed if you place a data click close to the first vertex of the fence.
4. Accept the fence contents with a data click.
This classifies the points inside the fence. You can continue with step 3 if you want to change settings, or with step 4 if you digitize the fence with this tool.
5. Use Save points or Save points As commands in order to save changes to point classes permanently into a laser point file.
