Text boxes have been painful since the inception. Why not make them work like modern text boxes of, oh lets say, the last two decades. The text box on this website is better. Formating is difficult in drawings.
What You See in the input box, is Not What You Get on the face of the drawing. One has to click in the drawingn area to see if it came out right. Making bold or different font size requires ASCII programing, (sure easy enough) which turns into just another thing you have to learn to use proe/creo. AND TEXT WRAPPING! Set the size of the text area and have it text wrap. Make symbols easier to input to text box.
This is one of those areas that has been left behind but is used all the time. People who are new (and old) to the software go "wow this is like form 1980's". No wonder it takes so long to learn proe (creo, whatever). It doesn't appear to have any improvement in Creo 2.0 which is amazing.
