I am wondering if it is possible to force text to remain level regardless of the Label Rotation: Orientation setting. (Similar to rotating text in an ordinary object depending on the state of V~ and W~) Does the parameter AC_bLabelAlwaysReadable have something to with it?
The text is still orienting correctly within the context of the label – it’s the label itself that is rotated. You will need to use the LABEL_ROTANGLE (I think) to always keep the text horizontal. Haven’t looked into it myself, but that’s where I’d start.
