Does any one know how to convert STL file to solid file through Reverse engineering in Unigraphics NX and CATIA ? ?

About creating solid file from STL format.

If you import the STL file in NX, you can set an option to convergent modeling. In this case your STL file will work as a solid model.
Or you can use the Reverse Engineering modul to create your features for modeling.

Hope this helps!
