RE: Curved or circular text
I use a LISP program titled ArcText and got it for free at CADALOG some time ago. Seems to be touchy as to which end of arc it picked.
There is a pull down sub-menu that can be used in version 2+ of Acad. Problem here is that whoever loaded up Acad on to you computer when new, had to include the Bonus pack. Not just the standard package. Go to your Help file, an it will detail how to. Only thing before doing such, is that you must be in correct layer, and have intended STYLE defined. If the same as others, go, go go.
