Text Control

[FWMiller]

I have a design with text arranged in arcs with a radius of 80 degrees. Is there any way to control the font to keep a constant character height while editing the text or changing the arc or changing the rotation? I find that any time the text is edited the designer software changes the size of the text box and scales the text character sizing in some arbitrary way. And not necessarily proportionally in x and y. It gets particularly bad if you try to change which font you are using. I've never before seen software text control where you don't have direct control over the font height. Is there something I am missing or is the text manipulation really this limited? Is there a trick to getting multiple text blocks with different formats to have the same character height without just experimenting until it's close enough to look right?
