Extract 3D Loci from Point Cloud |
Model > Point Clouds Context menu |
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:
Select the point cloud.
Select the command.
The Extract 3D Loci from Point Cloud dialog box opens.

Extract Loci Points |
Enter the number of 3D locus points to extract, or drag the slider to select a number. The maximum number of 3D locus points that can be extracted is 500,000. When the Available Points exceeds the number to be extracted, Vectorworks extracts 3D loci from points that are evenly distributed in space across the entire point cloud. |
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.
