Leica Cyclone - Point Cloud Sub-Selection; Multi Pick Mode

Data Extraction Module 5.0 - Cyclone Basic Modelling

Multi Pick Mode
1) Multi-Pick mode allows the user to pick multiple points/objects in a scene without having to
press Shift.
2) In Multi-Pick mode, pick the white dotted point again to deselect this single point.
 Watch the status bar at the bottom to check your selection (number of objects
selected, layers, coordinates, or distances).

To model features within a point cloud, we need to select those points that represent the
features we are trying to model. We are able to do this by means of point cloud sub-selection.
1.2 Point Cloud Sub-Selection
The point cloud sub-selection commands are useful for isolating and modelling points in the
scene that may or may not be of the same scan. The point cloud sub-selection tools work in
conjunction with the
• polygonal fence mode
• rectangular fence mode
• circular fence mode
In the following exercise we will separate points that represent a building facade from the whole
registered set. In doing so, we will also create a separate ModelSpace View containing only the
points representing the facade.
1) With a viewpoint similar to Figure 3, draw a fence using the rectangular fence mode.
