NX10 python journal - how to iterate through operation navigator - geometry view 1

[Nikix]

Hello everyone,

At first thank all of you for such amazing forum, I am able to find answer to my question nearly everytime.

But now I am solving journaling via python in NX 10. I would like to ask you how to iterate through all operations in operation navigator - geometry view.

For example I have several programs in this tree, I would like to get operation name, feed, spindle speed, stock, tool, operation time etc.

Could anybody provide me info how to do it via python?

Thank all of you for answers.

Nikola

FYI there are many vb samples for this, if that helps. Look at the OOTB “CycleAll” samples in UGOPEN\SampleNXOpenApplications\.NET\CAM.

Below is a python sample that should give you a good start.

Hello Mark,

thank you so much! This is great example. I am playing with this code it is really works.

Thank you.
