If you're just looking for a hand-lettered-look font, and don't need it to actually look just like ARCHSTYL, I would suggest you use STYLUS, which comes with AutoCAD [no issues with sending drawings to other people who don't have your font], and in addition, is much better looking. I don't mind the general concept of emulating hand lettering, as "dishonest" as it is when you think about it, but at least it should be emulating good hand lettering, which ARCHSTYL [assuming it's the same one I've seen around a lot] definitely does not -- it's got some really ugly characters, in my opinion.
HOWEVER, be aware that when you use a .TTF font instead of a .SHX font, you give up some capability. Using lineweights based on colors in plotting, you can, for instance, have different parts of the same Mtext object at all sorts of different degrees of boldness, whereas you may not have any bold-face option with a .TTF font, or if you do, not likely more than two choices [regular & bold]. And in some cases at smaller sizes, even bold will look too light, because of the way a .TTF character is an "area" rather than made up of "linework," and therefore is unaffected by plotting options.
