Why do I need to reverse engineer?
All 3D models are not created equal
3D scanning produces a point map, or “mesh”, of an object’s surface that makes no distinction between features such as faces or holes. For many applications, the mesh needs to be converted into a solid model, such as an IGES or STEP file via reverse engineering.
These “dumb” solids can be used with most manufacturing processes to replicate your part directly. However, these files are not without their own limitations. STEP and IGES files lack the feature tree that you would have had you designed your part from scratch in a CAD package.
