3D File Formats in Engineering and CAD

In the field of engineering and computer-aided design (CAD), different 3D model file formats are used for sharing and editing complex models. Here is a presentation of the main formats we are able to supply, their characteristics, and the software capable of reading them. Please note that compatibility problems may arise if you do not have the latest versions of the software. The desired format must be stipulated before ordering and, if in doubt, do not hesitate to ask us for a test file.

You will find important information on our dedicated page on theIntegration of 3D/BIM model files in CAD/CAM software

Le choice of 3D file format is crucial to ensure smooth integration into the CAD software used. At 3D Scan Bat, we help our customers make the right choice of format to ensure data continuity and avoid import errors. This page shows you the formats available, their advantages, and the main software packages compatible with them, to facilitate your exchanges and your projects.

How do I choose the right 3D file format?

Le correct file format depends on the software you are using, the type of project (architecture, engineering, 3D printing, rendering, etc.) and the level of detail required. For example, an architecture office working on Archicad will prefer a PLA or IFC file, while a mechanical engineer will use a STEP file to guarantee interoperability between different software.

Our team masters the conversion of models from point clouds to a wide range of formats, while ensuring that the geometric and semantic integrity of the objects is preserved. When modelling, we adjust the levels of detail (LOD) according to the customer's specific requirements: visualisation, thermal study, structural simulation, etc.

Thanks to our experience with ArchicadIn addition to our expertise in BIM, Revit, Rhino, Fusion 360 and Blender, we know how to deliver files adapted to different workflows, whether for design, BIM coordination or client presentation. This expertise also enables us to anticipate the risks of information loss during exchanges between software packages, and to offer you a test file beforehand.
