How do I get an stl file from a point cloud?

Hello

After having carried out a scan of the interior of a commercial vehicle with a Faro brand device, I would like to be able to import it as a part on solidworks.

My scan is a .wrl file with a point cloud. I'm looking to convert it as an STL mesh or something similar. I started looking for solutions on the Meshlab software without any results.

Thank you in advance for your help

hello, have you tried to open it directly under SW, but it may remain at the state of a point to be confirmed.

Do you have a mini .wrl file as an example?

Import

The VRML converter imports all VRML files as SOLIDWORKS part documents. SOLIDWORKS assembly files exported in VRML format are imported into SOLIDWORKS as part documents. The VRML converter tries to integrate the VRML polygons into a volume. There are no non-planar surfaces in the imported file; they all are. This import option is intended to be used as a last resort for importing data into SOLIDWORKS. In many cases (especially in complex models), the resulting volume is unusable and the data is only useful for visualization purposes.

 You can import VRML files as graphics data, volumes, or surfaces. When you import VRML files as graphics data, you can select the Import texture information check box to import texture information if it exists.

After some research, it seems complicated to convert a point cloud into a mesh.

I enclose a thesis on this subject and a summary of it.

Basically, use the points to recreate the surfaces useful to the project. (it all depends on your needs)

---------------------------------------------------

The creation of a digital model of an existing building requires the survey of the building. The terrestrial laser scanner is widely used to achieve this goal. It allows you to obtain the geometry of objects in the form of point clouds. It provides a large amount of accurate data in a very fast way and with a high level of detail. Unfortunately, the shift from point cloud to digital mock-up is currently largely manual due to the large volume of data and processes that are difficult to automate. This process is time-consuming and error-prone. A major challenge today is therefore to automate the process leading to the 3D reconstruction of existing buildings from point clouds. The objective of this thesis is to develop a processing chain to automatically extract the maximum amount of information from the point cloud of a building in order to integrate the result into a BIM software.

Hello @mathis-renaud

For this problem you have to use Scanto3D which is designed for this. Looking here where everything or almost everything is explained.

This problem is regularly discussed on this forum, a little research should help you.

Note if you do more than once you have the Solidworks TOMORAMA Plug-in which is a more complete tool (but not free) (TOMORAMA from Geosat)

I don't have time at the moment but it would be worth doing a tutorial because reverse engineering is becoming more and more frequent or also like in your case @mathis.

Kind regards
