About the Source/Selection Filter

The source/selection filter is designed to allow you to define a set of points that is selectable within the profile dialog. This is particularly useful for excluding points (e.g., ground, and/or model key points) from the possibility of being selected and consequently edited.

The points that are selected when using the editing tools are an intersection between the display filter (i.e., points displayed on the screen) and the source/selection filter ( i.e., the points that can be selected). This means that points that are drawn on the screen will not be selected regardless if the source/selection filter includes that point. It is highly suggested that the display filter define a broader point set than the source/selection filter. A warning message will display if the source/selection filter includes a classification, return combination, or elevation range that is not included in the display filter (e.g., ground not included in the display filter, but included in the source/selection filter).

Tip A warning message may display if the source/selection filter defines a set of points that are not defined within the display filter for the active LIDAR Layer. This creates a situation where the source/selection filter is designed to select points that are not displayed on the screen. Please use caution when the source/selection filter is in this condition, as points not displayed on the screen are not selected and not modified as you choose.
