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

All Points Workbench tools can be accessed from the Points menu and the Points tools toolbar.

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.
- Fläche aus Messwerten (German)
- Schnitte durch Flächen aus Messwerten (German)

+All Points Workbench tools can be accessed from the '''Points''' menu and the '''Points tools''' toolbar.
-* [[Image:Points_Import_Point_cloud.svg|32px]] [[Points_Import|Import]]: imports a point cloud from a text file.
-* [[Image:Points_Export_Point_cloud.svg|32px]] [[Points_Export|Export]]: exports a point cloud to a text file.
-* [[Image:Points_Transform.png|32px]] [[Points_Transform|Transform]]: transforms a point cloud.
-* [[Image:Points_Convert.png|32px]] [[Points_Convert|Convert]]: converts to points.
-* [[Image:PolygonPick.svg|32px]] [[Points PolyCut|Polygon cut]]: cuts a point cloud with a picked polygon.

+* [[Image:Points_Import.svg|32px]] [[Points_Import|Import points...]]: Imports a point cloud from a file.
-At the moment the workbench has no automatic routines to deal with the imported points, but the user can use [[Python]] scripting to programmatically process the data.

-It is also possible to use the tools from the [[Draft Workbench|Draft Workbench]] to connect the points using Draft objects such as [[Draft Line|Lines]] and [[Draft BSpline|Splines]]. Using the [[Draft Endpoint|Endpoint]] snapping method will ensure that the tools snap to the imported points.
