To Assemble an NX File into a Creo Assembly Model
1. Open an assembly.
2. Click Component > Assemble > Assemble. The Open dialog box opens.
3. Select NX File (*.prt) in the Type box. You can also set the file type to All Files (*), Creo Files (.prt, .asm, .drw, .frm, .mfg, .lay, .sec, .dgm, .rep, .mrk, .int, .g, .cem), or Part (*.prt).
