**6. Conclusions**

In this chapter, technology that enables 3D shape engineering and design parameterization for reverse engineering was reviewed. Software that offers such capabilities was also evaluated and tested using practical examples. Based on the evaluations, we observed that *Rapidform* is the only viable choice for parametric solid modeling in support of 3D shape engineering and design parameterization. *Rapidform* offers CAD-like capabilities for creating solid features, feature tree for allowing roll back for feature editing, and very good sketching functions. In addition, the *liveTransfer*™ module offers model exporting to mainstream CAD systems almost seamlessly.

After research and development in decades, technology that supports 3D shape engineering and design parameterization is matured enough to support general engineering applications. The ideal scenario can now be realized by using software such as *Rapidform* for shape engineering and parameterization, where labor intensive tasks, such as managing point cloud, triangulation, etc., is taken care of in an automated fashion; and design intents

Major CAD packages, such as *SolidWorks* and *NX*, have been well supported. However, software such as *CATIA* is yet to be included and software like *Wildfire* needs to be streamlined.
