This article shows how to visualize the point distribution generated by NX for 3D motion.


NX 5 introduced an improved point distribution scheme for the smoothest possible surface finish on 3D geometry. This updated processing is now applied to all 3 axis tool paths.




Created with NX 5 



Activate the ability to visualize point distribution

To 'Turn On' the ability to display the actual point distribution, you must set an ENV variable:


1. Create a new ENV variable by doing XXXX, type XXXX

2. Enter the following in the New System Variable dialog:


  • Variable value: 1





Display point distribution

Once you've set the ENV above, you can now see the point distribution for each of your various operations by:


1. Start NX CAM (it is important to restart NX after setting an ENV variable for the change to take effect)

2. Open any operation

3. Replay tool path

4. Tool path will include visible points
