It's clearly visible in [text3d]'s helppatch, where, if you drag the first numberbox on the rotateXYZ object, you can see that the rotation axis is not centered.Can somebody help or explain ?
the "problem" is, that the justification ("center", "middle") uses the *font* properties rather than the actual text you are rendering. this is entirely intentional: in general you wouldn't want your text to jump, just because the text changed from "m" to "q" (characters starting to grow downwards) or "O" or even "Ö" (characters growing upwards).
the solution is of course simple to adjust to pivot point (the text around which to rotate) of your text to be in the middle of the vertical center of the bounding box.
to adjust the pivot point, use a [translate] *after* the [rotate] object. see attached modification of your patch. mfda IOhannes
