Hi @bentraje,

do you need that functionality to work in GUI mode? If so, here's an example video showing that Cinema 4D already provides that funtionality - a bit hidden though:

In P/S/R tool with a selected object, Ctrl+RightClick an axis (or rotation band). Release both to hover over a reference point, edge, axis, etc.
Left-Click and drag to a target point.

Another workaround I also use often, are guides. Set a guide to semi-line, so you have start - and end-handles. Snap the guide to the edge or angled wall.
Now you can either use Guide-Snapping or simply copy/paste the rotation.

The third solution would be to use dynamic guides.

Best,
Robert

No. c4d files are a proprietary format and I assure you, Maxon won't release the internal structure to public. ;)
Depending on what you achieve, there might be a solution by using the Melange SDK: https://developers.maxon.net/?page_id=1112

Can you elaborate a bit more what are you trying to achieve?

Here you go:

You should go for File->Export->FBX and tick text file.
But it highly depends on what you understand by "everything in the scene". Tool settings, Multipass-settings? 3rd party plugin settings, etc.?

You are using R20.038. Current c4dpy is 20.057. Maybe here's your mismatch?

How and where do you handle your thread? Do you use Thread.Wait()?

Thanks Sebastian!
Looking forward for a fix. ;)
Meanwhile I'll take care of your recommendation.

Best,
Robert

If you don't save, you are responsible to write any data on document close to a custom BaseContainer that is written to your object's container.
And read the container and restore the tag data on loading the document again.

Since tags belong to an object and objects are written to disk on save, your tag data should still be available on reload.
Otherwise, you could write a custom BaseContainer with your settings before Cinema 4D gets restarted.

Using requests package would be the solution I guess. Even the docs state that they are auperior on high level access.
The web says that urllib2 is broken in so many ways due to its age.
