Re: A stupid question

Alan, Greg,

Thanks for the reply. My reason for asking is it would be convenient
for me to use ACAD to draw some test shapes, convert them to a gerber
format using AutoGerb 3.0 and then output the results (after a little
editing) as a .txt file via a serial port to my "little black box"
project.
