This question already has an answer here:
I know it's not possible in CS5, now we have CC with more functions so does anyone know if there is a button to centre type vertically in a text box in Illustrator CC?
I am creating lots of templates with text boxes that have many different numbers of lines and are being edited frequently so type needs to sit in center of box vertically automatically. The workarounds in other threads do not help me, for example selecting the boxes elements above and below them to centre each time content is updated is not an efficient method as there are over 30 text boxes multiplied by 25+ templates.
QUESTION ANSWERED: This functionality is not supported in Illustrator CC.
