For direct curve and surface manipulation, the tool set supports relative and absolute movement of control points and poles.
Reverse engineering from physical models and scanned data benefits-from new tools in NX 4 that fit splines to point sets, facets, other splines or surfaces, with full control of tolerance and connectivity up to G2 continuity. Reverse engineering can begin by fitting surfaces instead of curves to scanned data or other surface geometry, with full control over degree and spans. NX 4 lets designers control and validate the surface fitting by selecting target and reference objects and specifying deviation ranges.
