After defining a point selection, use the Point Cloud tool to isolate, hide, filter and expand the selection. All actions have associated keyboard shortcuts.
Isolate and hide selected points
Isolate and hide points to make more accurate manual reclassifications.
Isolate points
Select points in the area of interest and click Isolate (V) to only show the points in the current selection and hide all other points.
Hide points
To filter the area down further, select points to remove from view and click Hide (H) to hide points in the current selection. It may help to change the position and orientation of the camera to see the selection from a different perspective.
Continue to isolate and hide points as required.
Step through the filter history
Retrace and reset the filter history using the following actions or keyboard shortcuts:
Reset Filters (
⇧ + H) - Removes all isolate and hide actions. Brings all points back to view.Prev Filter (
Q) - Removes the latest view filter (isolate/hide action) on the stack. See full history in the Filter History section.Next Filter (
E) - Re-applies the latest view filter (isolate/hide action) on the stack.
To view the full history of filters that have been applied in more detail, see the Filter History section in the tool.
Filter and expand selection by classification type
Select points by class
Chose the classification type to select using the Classification Type dropdown in the Options section, or the keybindings defined in the Reclassification Keybinds section. In this case, 'structure' is chosen.
Then select the area of interest.
Click Select by Class (F) to remove all points from the selection that are not of the selected classification type.
In this case, only structure points are selected now.
Exclude points by class
For the opposite effect, select the area of interest and click Exclude by Class (⇧ + F) to remove all points from the selection that are of the selected classification type.
In this case, all points except structure points are selected now.
Expand selection by class
Expand Selection (X) is identical to the Proximity Selection mode, however it can be applied to multiple points at once.
First select point classes of interest. In this case, structure and conductor classes have been selected.
It is not recommended to use this action when dense or expansive classes such as ground are in the active selection. Doing so will impact performance.
Click Expand Selection (X) to continuously selects more points of the same classification type(s) as the current selection.
The selection will continue until there are no more points to select within the configured radius of any selected point. Configure the radius in the Options section using Expand Selection Radius slider.
