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
- 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
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:
- Fläche aus Messwerten (German)
- Schnitte durch Flächen aus Messwerten (German)
- Inspecting Point cloud.
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.
