Two example files are attached; the SolidWorks model is 2016.
The basic idea is:
- Split the model into sections. The more sections, the more accurate the curve.
- Use the "reference point" tool to place a point at the center of each sectioned face.
- Insert a Curve Through Reference Points to create the center line
