Daniel - I haven't toyed much with the standalone version of XFoil; only enough to conclude that it wasn't very user-friendly. Profili does allow editing of airfoil coordinate points, as well as modifying camber, thickness, etc. Attached is a screen shot of the XFoil settings menu in Profili; hope it helps.
scole - The ability to laser-cut depends on the file format used by the cutting service. Profili can export airfoil data in 4 formats: .PRO, .DAT, .COR (used by CompuFoil), and .TXT. I'm sure your laser-cutting service uses at least one of these formats. Profili can also import files in .PRO, .DAT, .COR, and even
raster, e.g. bitmap (.BMP), formats.
. . . but its a pain to pay 15$ for something like this . . .
Shortman - Hope you're implying that the mode of payment is a pain, and not that software of this type is overpriced at $15 ?!? At that price, it's easy to underestimate XFoil, and assume that it simply plots charts or interpolates pre-loaded data. No, XFoil is a bona fide CFD program - Realize that were it not for Mark Drela and MIT releasing the program as shareware into the public domain, an equivalent commercial product would likely cost in the upper 3 figures, if not $1,000+. If you want to know the nitty-gritty that went into it (or need a cure for insomnia
