Point Cab


With PointCab Mesh Module, you easily extract 3D surfaces, 3D objects and digital terrain models (DTM) out of the point cloud and use them in your CAD system.

  • Area model of a facade

    Area model of a facade

    Scanning a facade using a laserscanner is a rather easy task , contrary to analysing and evaluating obtained data.With a help of our Mesh tool you can create a area model of a facade. In order to do it activate the Mesh tool :

    Activate Mesh tool

    Select inner area of the facade :

    Close the selection by selecting the its start point again :

    In Job Editor you can define area’s settings. In case of a facade meshing precision of 1 cm makes sense :

    Now you can start processing :

    After completing the processing, PointCab displays the mesh as a orthophoto.

    For further mesh analysis you can have a look on it in our 3D View. In order to start it open the Job :

    3D opens in a new tab. Left click to have a look on your 3D area model :

    The default position of rotation point is always in the middle of the project. To change it cha hold down the scroll wheel on your mouse and move the rotation point as you wish :

    Finally you can open the results in your CAD Program. Right click the Job to open its storage path :

    Now select a CAD file :

    A facade model as DWG in TrueView :

  • Solid model of a buildings facade

    Solid model of a building facade

    Do you need definite points to import to other system for further evaluation ? With our tool to export 3D points you can do it :

    Create the area for every facade:

    Go around the building. Pay attention to reasonable placement of section areas. The inner boundary should be placed within the walling. Aditionally the direction of projection should be from outside to the building .

    The calculation of all facade plans can be startet by clicking Process All Jobs :

    Now open all facades and activate our Mesh tool :

    Select only the inner area of the facade:

    Next start processing :

    As soon as processing is over, the mesh will be displayed as an orthophoto. Open the 3D View :

    You can now have a look on all facades of the building :

  • Surface model of a mound

    Surface model of a mound

    In order to create a mesh of a mound , activate our Mesh tool:

    Select the area you wish to evaluate:

    The selection is completed when you select the start point again:

    Now you can set the parameters of the project. You can do it in Job Editor:

    After the calculation you can have a look at your result in 3D View. You can open it by double click the Job or in the Context menu (right click) :

    You can have a close look at your surface in a 3D View :

    Of course you can continue analysing the mesh in your CAD Software. In the Context menu you can show your result in the folder:

    Below an example of a mesh as DWG in TrueView :

  • Digital terrain model

    Digital terrain model

    With our Mesh tool you can create a digital terrain model. Activate our Mesh tool:

    And choose the area of the DTM:

    Start the processingwith the green start button. The result will be shown directly as an Orthophoto :

    You can open the mesh directly in our 3D View :

    Or you can import the result to your CAD Software. Below for example a DWG was created and opened in Trueview :

  • Mesh settings

    Mesh settings

    In Job Editor you can edit different settings to match the result to your requirements.


    The mesh accuracy describes the maximal acceptable divergence between calculated mesh area and measured point cloud.The smaller this value, the minuter the location of triangles. In consequence the size of a file augments.

    The filter object smooths the surface and removes points within some value. It means that if a 5 cm filter is selected , points lying 5 cm above or below the surface will be ignored. If a prism pole stands in the terrain, it will not affect the calculation.

    CAD & File

    CAD & Datei

    Under the CAD tab you can choose the Export Unit. In this way you can export your meshed surface in milimeters directly to your CAD Software.

    You can change the name of a task under File. In addition to DWG file you can also output a DXF or DAE file depending on in which CAD Software you want to continue your mesh processing.
