the question is simple - how to copy all the attributes of the curve data to another curve object by python? I need to make it look the same - same cutom bevel, same extrude, same offset... same attributes. Is there any simple python solution?
I think I've solved it! Instead of copying all the attributes (that would be overkill) I discovered - If I will join the curve into original curve - it will inherit all the properties. So I do that in python and then delete old curve data. Of course first I have to match all transforms... If I won't move the pivot, it seams like it's working!
