Point Cloud
This format is rarely needed by end customers and is included here only for completeness.
A point cloud is the simplest representation of a 3D object, made up of coordinates (X, Y, Z) that define points on the scanned object’s surface. Point clouds are usually used as an intermediate format for creating meshes (i.e. STLs), or for academic research and analysis.
When to use Point Cloud
- Only when the task specifically require it
- With a scripted or automated process
- Deviation analysis (mesh is normally preferred)
Compatible software
Most 3D modelling packages can open point clouds, but functionality varies. Commonly used software packages include: CloudCompare, Meshlab, PolyWorks, Geomagic, ZEISS Inspect
Need point cloud data?
Our 3D scanning service captures precise surface geometry.
File Specifications
- Extensions: .txt .asc
- File Type: ASCII Text
Mesh Model
Meshes are the standard output from 3D scanning and the primary format used for 3D printing. They are triangulated surface models that can provide true, accurate representations of your physical part.
Watertight vs open
When scan data does not achieve full surface coverage, intentionally or not, the resulting mesh will contain holes and gaps. This is referred to as an open (non-watertight) mesh.
For applications such as 3D printing, the mesh must be watertight, meaning it forms a fully closed surface with no holes so that a solid volume can be defined.
If a scan produces an open mesh, it can usually be made watertight using post-processing tools.
When to use Mesh Models
- 3D Printing
- Reverse engineering starting point
- Visualisation / preservation (digital twin)
- Inspection / deviation analysis
Compatible software
Most CAD, inspection, and rendering software can open mesh models, though the level of editing and measurement capability varies.
Commonly mesh editors: MeshMixer, Blender, Geomagic
CAD packages with mesh support: Solidworks, Quicksurface, Autodesk Fusion, Inventor
Need mesh models for your parts?
Our 3D Scan to STL service delivers print-ready files.
File Specifications
- Extensions: .stl .obj .ply
- File Type: Binary or ASCII
All three files contain identical geometry in different formats.
Surface Model
Surface models provide a CAD-ready representation of a scanned object using mathematically defined surfaces, typically NURBS (Non-Uniform Rational B-Splines). They are useful when you need a true CAD surface rather than a triangulated mesh, for example when your software cannot handle meshes, or when you want to create solid models from freeform geometry.
Open vs closed surfaces
Like meshes, surface models can be open or closed. A closed surface model can usually be converted easily into a solid body for further CAD operations.
When to use Surface Models
- Creating solid models of freeform or non-prismatic shapes
- Accurately representing a part as CAD surfaces
- Viewing scan data when a mesh isn’t an option
Compatible Software
Most CAD packages that support STEP models can work with surface models.
Common tools: SolidWorks, Autodesk Fusion, Inventor, Siemens NX, CATIA, Rhino
Need CAD-ready surfaces?
Our Scan to CAD service creates NURBS surface models.
File Specifications
- Extensions: .stp/.step .igs/.iges
- Type: Neutral CAD
Design Intent Solid Model
A design-intent solid model is a CAD body, typically created using parametric modelling to capture the part’s intended geometry. These models are ideal for manufacturing or when an easily editable CAD model is required. They can be supplied in either a neutral format, which offers broad compatibility, or a native format, which retains the feature tree and allows full parametric editing.
When to use Design-Intent Models
- CAD to be used in manufacturing
- Redesigning a component
- Engineering analysis or simulation
Format Guidance
- Neutral format (STEP / IGES): widely compatible, suitable for sharing or importing into most CAD systems; retain all geometry but not the feature tree.
- Native formats (SLDPRT / F3D / IPT): preserves the feature tree but can only be opened by the associated software.
Compatible Software
Most 3D CAD packages support most neutral formats, plus their own native format.
Example CAD software: SolidWorks, Autodesk Fusion, Inventor, Siemens NX, CATIA
Need parametric CAD models?
Our reverse engineering service delivers production-ready designs.
File Specifications
- Extensions: .stp/.step .igs/.iges .sldprt .f3d
- Type: Neutral or Native CAD
2D DXF Drawing
DXF is a widely used file format for 2D CAD drawings. It is ideal for transferring 2D designs between CAD systems or for preparing parts to be cut, engraved, or machined from sheet materials such as metal, wood, or acrylic.
When to use DXF
- Laser cutting, waterjet, or CNC machining of sheet materials
- Creating 2D layouts or templates
Compatible Software
Most CAD software can import and work with DXF files.
Common tools: AutoCAD, SolidWorks, Fusion 360, DraftSight, Rhino, CorelDRAW
