Full disclosure, I just realized that in "Axis Modification" Tool, when in Polygon mode, if you hover over an edge and click, it places the Axis there...
I guess most of what I was trying to do is already there...

Thank you very much.
The "swizzling" can be achieved with the Axis Center:

using these settings.
BUT the code you posted is very valuable for me to evolve my spaghetti coding... copy from here, and paste there :-)

Thanks Again!

thank you so much for the detailed reply, and helping me save a lot of time by not doing it that way after all :-)
I am trying to come up with a "shortcut" method for something I'm doing a tutorial on.
All the functionality is already possible inside C4D, but to set it up you need to do a bunch of things and set a bunch of settings.
The "manual" way is:

1. Use Axis Center to align and Center the Object Axis to the Selected Edge.
2. Set the Modeling Axis to "Object"
3. Change Component mode to Polygons
4. Select your Polygons
5. Use Quantizing to Move or Rotate the said Polygons.
   All this could be possible via a script, instead of doing Matrix math :-)
   Thank you very much again for your input!

Here's a number of "loaded" questions, as I have a goal in mind:
Is it possible to do the following things via a script, when we're in Polygon Component Mode:

1. when the script is activated, although we are still in Polygon mode, can we see Edge selection highlights when the cursor is hovering over some edge
2. by clicking on that edge, could we set the Modeling Axis to align to the Center of the edge, and the modeling Z Axis to align to that edge?
3. After the Click (on the edge) can we exit the script and use that Axis as the modeling Axis?
   Would those be possible?

Ah, you probably expect the toroids to also rotate around their own axis

exactly. Thanks

@m_adam said in Using Python Node to Traverse Deep Hierarchy... fail:

The main issue is Python GvNode is not designed to work as an iteration node

Thanks. That answers my question.

In the attached example, I am using a Python Node to traverse a hierarchy, and although I can print the name of each child in the console, the OutputObject refuses to pass through and affect the next Object node. What am I missing here?
How do I force the object to "export" inside the while loop.
If that's not possible, what's the easiest way to do that hierarchy traversing?

Oh man... thank you so much. Even when I read your reply, I couldn't "see" it in the Node... was staring at it for to long.
thanks.

Python Hierarchy Node 11A.c4d As I'm trying to understand how to use a Python Node in XPRESSO, I did this very simple setup. All I want is for the "OutputObject" to be the same as the "Input1" but I keep getting an error: "NameError: Could not find port value for 'OutputObject' in node 'Python iterate Hierarchy'."

Can someone explain this please?
Cheers
