• 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.

Unigraphics NX software

NX is an interactive Computer-Aided Design, Computer-Aided Manufacturing, and Computer-Aided Engineering (CAD/CAM/CAE) system.

Creating Solids• Sketch a desired shape (two dimensional) and then turn it into a solid (three

dimensional) by applying a desired operation.

Create a feature from the sketch by extruding, revolving, sweeping, lofting and blending.
