Point Cloud Exportチュートリアル
With the Point Cloud Export module, you can export specific sections of your point cloud.
Due to filters, you reduce the size of your point cloud output additionally.
If you import the data afterwards into a CAD system, for instance, you facilitate and accelerate your work significantly.
Direct RCP Export
PointCab allows point cloud export into AutoCAD RCP format. Thus, you can import data directly into AutoCAD without the need for ReCap and without loss of time.
Together with the automatic export filter (Octree), just the required scan points are loaded in your CAD system provided that the required accuracy is respected.
For more information, please move your cursor on the markers.
Export point clouds using the example of a mansion
1．Select the tool “Export point cloud” and select the zone in the standard top view. Edit the selected zone by defining the upper and the lower border.
Select the desired filter in the Job Editor (on the right) and set further output options.
Scan points: The number of scan points is reduced additionally by the chosen factor. If you choose the factor “2x”, just each second scan point is used.
Block filter (octree): The number of scan points is thinned spatially and thus homogenized. If you select a block size of 0.05m, just one point is exported in a cube of this edge length. That’s why almost all pieces of information are maintained in areas with low point density.In areas with high point density, redundant points are excluded.
The filter can reduce the point cloud enormously without losing essential information; it significantly speeds up the subsequent work with the exported data, e. g. in the CAD system.
Height points (“elevationt profile”): You get the grid-shaped DTM as a point cloud for the respective layout or sectional view. The number of points depends on the image resolution selected originally for the layout or section.
In order to avoid vegetation widely, you create a layout and inverse the diretcion of view – thats means bottom-up. When you use the height point filter for export, the “surface” is found and not the “vegetation”.
A predefined scan radius is ignored during point cloud export.

RCP: Autodesk RCP format. Import data directly in AutoCAD without the need for Autodesk ReCap.
4． Start processing the export in the Job List.
5． Now, the generated point cloud file (Open by right-clicking: /projectname/projectname_Results/3D/) can be imported in any desired CAD software. Or you create a new PointCab project based on the point cloud.
