Intellectual Technology LimitedProvide Expertise to Siemens NX Users in China and Hong KongSiemens NX 6 Surface Modeling - Mouse
Tutorial 2A - Import 2D outline drawing into Siemens NX 6- Build 3D curves based on the imported drawing- Build the upper surfaces of the mouse
Tutorial 2B - Do the draft analysis to search any undercut portion on the upper surfaces- Build the lower surfaces of the mouse- Convert the surfaces into a solid (Master Model)
Tutorial 2C- Build the parting surfaces based on the imported drawing - Create components from the finished model- Create a new part in the assembly (Design in Context)- Modify a part design while looking at other parts (Design in Context)
Please be reminded that this series of tutorials is designed to demonstrate a design approach with Siemens NX, rather than the command itself. For the details of commands, please read the online help or attend the software training.

These eye-catching visualizations allow users to easily see business results and trends, allowing them to take immediate action to improve performance.
Advantages of Analyzer 2007:
Easy to Deploy
Easy to Use
Low Total Costs
Analyzer is being used successfully within a variety of industries such as banking, finance,
technology services, manufacturing, real estate, healthcare, insurance and others. The examples
are CITI, Loreal, Bosch, Johnson & Johnson, and 7-Eleven.
