I purchased their software, Font 2 DXF and G-Code 3.1 and it appears to produce good quality dxf fonts, but I'm having trouble setting the parameters to produce letters in an arch. I keep adjusting the parameters and either nothing happens or weird stuff happens. I know I ain't the smartest fella but I figure this should not be a difficult thing to do.

I do my dxf drawings in Draftsight, and using Font 2 DXF, I can turn ANY font into a dxf font, then copy it into my drawing, and then rotate and place each letter as needed. But I'm sure that Font 2 DXF can do that for me with a lot more precision . . . or so I think.
Thanks,
Tom
