"Reverse engineering is the process of taking an existing part and digitizing it. There are several reasons to do this - it may be a legacy part that doesn't have an existing CAD model, implement existing concepts from other products that work well, or create a repaired model from a damaged part. This can be achieved by: 1. Measuring features manually and creating a CAD model from scratch 2. 3D scanning the part and creating a mesh 3. Creating an editable parametric model based on a scanned mesh Some features may require using manual measurement, like high aspect ratio holes (depth >0.5 x diameter), to be added on top of scanned geometry."
