Version conflict FARO Scene 5.2

Dear PointCab’ber,

for those who do not yet work with the current version of Scene 5.2 , and have edited your project in PointCab 3.0 (R12 ) , will experinese that the FARO project can not be opened in the old Scene version .

The following error message appears:

Error Code FARO Scene

Error Code FARO SceneS

We are already working with the current interface of FARO Scene 5.2 (the FARO SDK) and this interface will overwrite the existing project to a FARO Scene 5.2 project.

This problem is already known at the FARO development department and we will adjust it with the next update of the FARO SDK.

However, you can avoid overwriting your FARO Project without update to FARO Scene 5.2 with a small detour .


Before you use your point cloud data in PointCab simply create a local workspace of the project in Scene:

create local workspace

create local workspace

With this function FARO Scene creates another file, that can be used to import the scan project in PointCab as an alternative to LSPROJ-file.

Please do not use the FWS-file to edit your project in Faro Scene – use the LSPROJ- file as usual.

If you already have incompatible data:

If it is already to late you can use the trial version of FARO Scene 5.2 to finish your project. You can find the free trial version of FARO Scene here.

Once the new FARO SDK is there, we will immediately inform you.

Thank you and best regards.

We get asked a lot if it is possible to use PointCab results in BricsCAD. The answer clearly is YES. We have prepared two videos to show you how to easily import PointCab Layouts and Sections and also 3D-Meshes (digital 3D terrain models) into BricsCAD. See how the pointcab Tools work and start using laser scanning data and point clouds in BricsCAD. If you have questions please feel free to contact us under at: Here you can get to the PointCab modules and Tutorials.

What is the correct resolution for my laser scanner?

Here, the principle is: Don’t scan as detailed as possible but as detailed as necessary!

The graticule

In order to make the correct choice, we want to explain the basic principles.
The laser scanner transmits a laser signal that is reflected by the object. Within the process, the room/object is scanned automatically and successively by the laser. Thus, a graticule is generated that is determined by the angular step size (horizontal and vertical circle) and the distance from the scanner to the object (intercept theorem). The lower the selected resolution, the bigger the angle between the single measured points of the laser scanner. Consequently, the distance between the single measured points is higher.

Distance between measured points

In figure 1 and 2, we show how the distance between scanner and object affects the distance between the measured points.

The distance between two measured points increases with the distance to the measured object.

1/2 4x 30:34 174,8 3,068
1/1 2x 30:34 699,1 1,534

The chart shows how the resolution affects time and point distance. That’s why it is very important to reflect about the optimum resolution for your project.

The following images of a scan cloud give you an idea of the various resolutions.

Overview of scan resolutions

Scan with 1/20 with quad quality in a distance of 7m


Scan with 1/10 with quad quality in a distance of 7m


Scan with 1/5 with quad quality in a distance of 7m


Scan with 1/2 with quad quality in a distance of 7m


Summary – Correct resolution for your laser scanner

In order to decide for the perfect scanner resolution, it is important to keep sight of the definition of task. Finally, laser scanning has to be economic. That is only guaranteed when the ideal parameters are chosen. You should pose the following questions:

Is it outdoors or indoors?
How big are the distances between scanner and object?
How many scans will I do in order to avoid shadowing?
Do I need colored point clouds or is a grey point cloud even more informative?
How do I process scan data and with which software can I do this?

The longer the distance to the object, the higher the resolution has to be. For a house facade with brick slip cladding without any decoration, for instance, a resolution of 1/4 and dual quality would suffice. But it is more important to avoid shadowing by using many laser scanner positions.
