How to arch text like this

I have tried that - and it distorts the text.  This applies a symmetrical arch without distorting the letters.  If you notice in the picture, the text box is straight across the bottom.  I want to know how to do this in a uniform manner. 

You will have to try again because that is how its done...arching the text at all is distorting the text...this is very quick with the envelope...had I spent time horizontally kerning it would line up perfectly to your example with one pull of the envelope...

You can also edit the text inside the envelope with your text tool or copy this envelope shape to other text/objects...

somecalmetim is using the correct Envelope mode, Single-arc.

With Single-arc mode selected you can drag any of the four sides and it will create a perfect arc (the envelope box that is, but not necessarily the content) without having to change or delete any box nodes or lines.
If you drag while pressing Ctrl, the opposite side will move in the same direction, and if you press Shift it will move in opposite direction.
Very useful.
