Introduction
The Points Workbench offers specific tools for working with point clouds. The workbench is still in development.
A point cloud is a collection of points in 3D space. A point cloud is generally produced by scanning the surface of a solid object. The cloud of points can then be used for many purposes including building a mesh for the object, reconstructing the surfaces and solid volumes, reverse engineering, as well as for visualization and quality inspection.
Tools
Import Point Cloud: will import coordinates for 3D-points from a text file
Export Point Cloud: will export coordinates for 3D-points to a text file
Polygon Pick: to do
Import Points…: Imports a point cloud from a file.
Export Points…: Exports a point cloud to a file.
Convert to Points: Creates point clouds from shape objects.
Structured Point Cloud: Creates a structured point cloud from the points of an existing point cloud.
Merge Point Clouds: Creates a point cloud by combining the points of two or more point clouds.
Cut Point Cloud: Cuts points from point clouds.
Notes
- Draft commands such as
Draft Line and 
Draft B-spline can be used to connect the points in a point cloud. Use 
Draft Snap Endpoint to snap to the points. - Python can be used to analyze and process point clouds. See the following forum discussions:
- Inspecting Point cloud.
