• NX is an interactive Computer-Aided Design, Computer-Aided Manufacturing, and Computer-Aided Engineering (CAD/CAM/CAE) system.
• NX is the commercial CAD/CAM/CAE PLM software suite developed by Siemens PLM Software.
• NX is widely used in the engineering industry, especially in the automotive and aerospace sectors.
• NX has some presence in the consumer goods design sector.
Unigraphics NX Software
• The CAD functions automate the normal engineering, design, and drafting capabilities found in today's manufacturing companies.
• The CAM functions provide NC programming for modern
machine tools using the NX design model to describe the finished part.
• The CAE functions provide a number of product, assembly, and part performance simulation abilities, across a broad range of engineering disciplines.

Surface Modeling in Unigraphics (NX)
This command creates a sheet or solid body through a set of up to 150 section strings. A section string can consist of a single object or multiple objects, and each object can be a curve, a solid edge, or a solid face. Through Curves is similar to a Ruled Surface, except that you can specify more than two section strings. You can also:

Through Curve option
This command creates a body from sets of primary and cross strings. Strings in each set must be roughly parallel to each other and non-intersecting. Primary strings must be roughly perpendicular to crossing strings

Sample of a Multiple Triangular Patch Surface
N-Sided Surface option
This option lets you build a surface with an unrestricted number of curves or edges that form a simple, open or closed loop, and assign continuity to outside faces. You can remove holes in surfaces that are not four-sided. Shape control options are available to refine sharpness at center point, while maintaining continuity constraints.

Surface Modeling in Unigraphics (NX)
Use the Studio Surface command to create swept or lofted surfaces from a network of section strings, or a network of section strings and up to three guide strings.
Section string (1), guide strings (2), and resulting studio surface
You can modify a Studio Surface without rebuilding it by adding, removing, reordering, or swapping section and guide strings. Studio Surface also lets you specify constraining faces and continuity, edit surface alignment points, and control the transitions between surface sections.
