Convert mesh to engineering CAD software solid part

As to me, I wonder whether it can be transformed into the format of sldprt in solidworks so we can revamp the model more accurate. Thank you for your excellent work.

Conversion from mesh to engineering CAD software solid part is a mostly unsolved problem. See details in this topic: Use segmentations in CAD or FEM software

How can you make the model more accurate in a CAD software where you cannot even see the original image and model in the same view? What would you like to achieve?
