How do I add a tag to an object? I have no problems cloning tags, like this.
BaseTag* tagFound = someObject->GetFirstTag(); BaseTag* newTag = (BaseTag* )tagFound->GetClone(COPYFLAGS_0, NULL); anotherObject->InsertTag(newTag, NULL);
But how do I
a) Insert one of the C4D built in tags, like the Constraint tag
b) Insert one of my own tags.
For (a) I just do not know. For (b) I get error messages. Mainly because my tags are
class MySpecialTag : public TagData
and I get complaints about MySpecialTag not being a BaseTag*.

You will need to include the modules/ca/res in your search path and include "Tcaconstraint.h" in order to have the enumeration.
BaseTag* tag = BaseTag::Alloc(MYPLUGIN_ID); if (tag) obj->InsertTag(tag, NULL);

You can have it even easier:
BaseTag *tag = obj->MakeTag(Tcaconstraint);
This will allocate and insert the tag in one single call. Don't forget to check the result for NULL, though.

Well, I think that I have had issues with adding undos using MakeTag(). But if that behavior has changed, by all means use that instead.

Thanks a whole bunch! I will test it out, as soon as I have sorted out a few other issues. And Undo is important, yes.
