The deliverables of 3D scanning and reverse engineering can vary depending on the project’s requirements and end applications. In this blog, we will explore the various deliverables of 3D scanning and Reverse engineering with their use cases.
Point cloud data is a common output of laser and LIDAR scanning techniques. It consists of a collection of XYZ coordinates that represent the spatial positions of points on a physical object. These points collectively form a detailed and accurate representation of the object’s shape and structure in a digital format.
Portable arms, LIDAR scanners, and DRONE-based lidar scanners produce the direct point cloud output that can be exported as.ASC ,.Obj and the below file formats

Mesh models are generated by converting point cloud data into a surface mesh composed of triangles or other polygonal shapes. These mesh models are commonly utilised for visualisation, analysis, and 3D printing purposes. However, it is important to note that mesh models are not ideal for design modifications or direct manufacturing. Making changes to mesh models can be challenging unless you have specialised sculpting tools like Geomagic Freeform. These tools enable more intricate modifications to the mesh model, allowing for design alterations and further manufacturing processes.Typically mesh models are exported as .STL files. Our 3D scanners directly deliver Mesh models in .stl file format.

Mesh models with texture
When the object is 3D scanned with texture using colour 3D scanners like Einscan , Faro Focus 3D Artec eva or any 3D scanners that have got the ability to 3D scan the colours , mesh models can be delivered with texture , below are the formats that support the textured mesh models.

CAD Models In Neutral file formats
The final outcomes of the 3D scanning and reverse engineering process are CAD models. Specifically, history-based CAD models are crafted by utilising point cloud data or mesh models as references. This is accomplished through specialised reverse engineering software like Geomagic Design X. This software comes with a parametric feature tree, which allows these CAD models to be edited ,optimised and also employed
for manufacturing purposes.
Make Design Intent and As-built cad models in Geomagic Design X which are tailored to the specific applications they will ultimately serve.
When it comes to exporting these CAD models, they are exported in formats like IGES, STEP, SAT, and PS.

History based CAD models in CAD software formats (Live Transfer )
Sometimes, users may require a CAD model that possesses a fully editable history, allowing for convenient design modifications in their own CAD environment. To facilitate this process, the reverse engineering software Geomagic Design X offers a feature called “live transfer.” This functionality enables the seamless transfer of the entire modeling history to most CAD software in the market. Essentially, instead of using CAD software directly for reverse engineering, one can leverage the capabilities of reverse engineering software to perform scan-to-CAD operations. Subsequently, these features can be utilized to transfer the obtained data to the CAD model, ensuring that the output is editable within the user’s own CAD environment.
The outcomes of 3D scanning and reverse engineering can vary based on the project’s needs. This can include point cloud data, mesh models, as well as CAD models both in their native formats and within CAD software.
Leveraging these outcomes, engineers and designers have the opportunity to enhance their designs, cut down on development time and expenses, and ultimately create top-notch products that align with their customers’ requirements.
