The Point Cloud tool is used to view, manually reclassify and export point cloud datasets which have been imported into Neara.
Open the Point Cloud tool in the toolbar or using the keyboard shortcut Y.
The tool actions and configurations will appear in the Properties panel.
Actions
Find available actions and keyboard shortcuts at the top of the tool panel.
All actions require one or more points to be selected first. Learn how to define a point selection in this article.
Some actions require a Classification Type to be chosen as well. This can be set in the Options section of the tool.
The available actions are:

H) - Hides all selected points.Reset Filters (
⇧ + H) - Unhides all points.Prev Filter (

Reclassify (
R) - Reclassifies all selected points to the selected Classification Type.Revert (
D) - Reverts all reclassifications made on the selected points.
Selected Points Table
Under the actions is the selected points table, where a point selection can be exported as a LAZ, CSV or TXT file. Expand the table to see information about the currently selected point(s).
If multiple points are selected, the table will look like this:
The table can also be used to reclassify, select, isolate (show only) and hide points by class, however it is recommended to use the tool actions and keyboard shortcuts instead of clicking through this table.
If one point is selected, the table will look like this. This is identical to what is displayed in the Properties panel when the default Move and Select tool is active:
Options
This section is used to configure classification type, and selection options.
Classification Type - Choose the point cloud class that will be used for the Reclassify, Exclude by Class and Select by Class actions.
When chosen, the action buttons will display the class for visibility.
The Classification Type can also be set using keyboard shortcuts, which can be configured in the Reclassifiction Keybinds section.

Reclassification Keybinds
While the Classification Type can be updated in the Options section of the tool, optimise for speed by configuring and using the chosen keyboard shortcuts in this section.
Configure the keys 0 ~ 9 to correspond to commonly used classification types. Using these keyboard shortcuts will then set the Classification Type in the Options section of the tool.
Filter History
This section contains the history of all the view filters (isolate/hide actions) that have been used. It displays information about what was isolated/hidden, and provides the ability to step through and re-apply various filters that were applied in the past.
