use python commands to further process your data, see discusion [http://forum.freecadweb.org/viewtopic.php?f=13&t=15988 here] and [http://forum.freecadweb.org/viewtopic.php?f=13&t=16103 here] (german sub-form).<br />

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.
Of course you could also use the draft workbench within FreeCAD and connect the points using draft elements.<br />
Using snap-mode "end-point" will ensure snapping to the points.

Introduction

The Points Workbench is intended to give you 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. Then the cloud of points can 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 of parts.

Tools

Limitations

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.

See the discussions in the forum:

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