Reverse engineering is the process of deducing design intent from an end product with little or no information about production procedures.

On this project, our customer wanted a solid CAD model built from laser scanned data from an original part. It was also requested that some of the features found on the original part were removed during the CAD modeling process. In the photos pictured here, the original scanned model can be seen along with the finished CAD model. Notice that the “slotted” features on the face of the club were not included on the final model. This was accomplished by mesh editing. Mesh editing is one of the many tools one can use with specialized software when creating solid CAD models from mesh data. In this case, feature editing took place on the mesh model before the solid model was constructed.

Other traditional CAD modeling tools are also built into the software. Using these types of tools, such as: extrusions, revolves and sweeps, new features can be created or existing features can be edited. Utilizing this type of dedicated reverse engineering software, we can create solid CAD models from virtually any real world object!
