Hi,

I am still new to C4D Python but not Python in general.

I was wondering how one would go about grouping some objects of a selection into a group, as in selecting some objects in the Object Manager and hitting Ctrl+G/Cmd+G.
It would be great if there is some sort of a command that takes a list of c4d objects and groups them.

However, I have been looking at the Python class hierarchy of the c4d module but I wasn't able to find something to do with grouping.

Thanks for reading!

Is this what you are looking for ? 🙂

PS: I'm sorry if there's any mistake in list comprehension etc. I am currently on a mobile device.

That Group function is exactly what I was looking for. Thanks a lot!

One question, if I may:

Why the

if op.GetDown() : return op.GetDown()

in

GetHNext()

?

If you want to return next then why go down and stop there?

No problem. 🙂

You somewhere need to go down in the hierarchy.
And going down has the highest priority while walking the hierarchy.
Hard to explain, just test a bit with it.
