I was hoping someone with direct experience with Scan to 3D would comment first. Unfortunately I don't have it in my license as I am on the Standard version. Based on what I have read here on the forum over the last several years, Scan to 3D has limited usefulness, so the return on investment might be better a different solution.
I was curious about the VX modeler, so I watched the video. It appears it cannot generate a complete nurbs model, so you would need to trim or construct additional surfaces in SolidWorks. You might also look at Rhinoceros with the Mesh2Surface and RhinoResurf plugins.
On the high end there is Rapid Form's Design X, which generates a fully native SolidWorks model (with the Feature Tree).
Another thing to consider is the resolution on the Creaform scanners may not be sufficient for your application.
