Note though that the actual panels will always be straight panels, so if your CW does not define automatic panel lengths (i.e. something like a max. panel width / height) you might find that it will simply draw a straight panel between the ends of the arc. So ensure you set the CW type's properties such that it will draw at least 2 panels across the circumference of the arc. You can change it later to fine-tune as you'd like, but you need something to start off with. It's not necessary, but at least it doesn't look like you've done something wrong from the start.
Note if the ribbon doesn't display the arc tools after you've started drawing the wall, go to the Modify tab. They should then be the last panel in the ribbon called "Draw".
