Extracting 3D loci from a point cloud

Point cloud scans of existing terrain can be used to create a site model by extracting 3D loci from the imported point cloud. The 3D loci are then used as source data for the site model. (See Editing point cloud objects to prepare the point cloud before extracting the 3D loci.)

To extract 3D loci from a point cloud:

1.      Select the point cloud.

2.      Select the command.

The Extract 3D Loci from Point Cloud dialog box opens.

Click to show/hide the parameters.

3D loci are created in the locations of point cloud points and are automatically selected, so they can be used immediately to validate source data or to create a site model. The original point cloud object is not modified.
