Failed to Load Chapter 1: Introduction What Is NX Open NX Open is an Application Programming Interface (API) that lets you write programs to customize or extend NX.

9 The benefit is that applications created this way can often speed up repetitive tasks, and capture important design process knowledge. There is a broad range of NX Open functions, which provide capabilities like Creating part geometry, assemblies, drawings, and CAE and CAM objects Cycling through the objects in a part file, reading information or performing various operations on them Creating custom user interfaces that allow users to select objects and enter data Some typical applications of these functions are: Creating part geometry or drawings according to your local standards Importing data from other sources, outside of NX.

10 Reading data from objects in a part file, and writing it out in some form of report Building custom applications to make processes faster or easier to understand Of course, these are just a few examples of what is possible. You can probably think of many little repetitive processes that you would like to automate to speed up your work or standardize your output. If you'd like a little more background information, please continue reading here. If you can't wait, and you just want to start writing code immediately, please skip to chapter 2, where we show you how to proceed.
