Why Point Cloud Data Beats STL for Real Engineering Work If you’ve been looking into 3D scanning for your business, you’ve likely come across terms like STL, OBJ, mesh, and point cloud. On the surface, they all appear to represent the same thing—a digital version of a real-world object. In reality, the difference between these formats can determine whether your project moves forward efficiently or stalls inside your CAD environment. Not all scan data is created equal, and more importantly, not all of it is usable for engineering. A common scenario is this: a company invests in 3D scanning to capture an existing component or piece of equipment. The intention is to modify a design, reverse engineer a part, or produce drawings for fabrication. The scan is completed, and the deliverable is issued as an STL or OBJ file. At first glance, everything looks correct. The model opens inside platforms like SolidWorks , Autodesk Inventor , Autodesk Fusion , or Onshape . However, as soon ...
