I am new to the stone industry and we have just purchased a cnc machine that operates using Briscad. We do all of our post-production files in Autocad 2007. We are now starting to engrave stone and would like to know what would be the best program to use which would allow us to export text and drawings as dxf files? I know its really a matter of personal perference (to some degree), but what is everyone else using for this purpose?
