using VW 11.5 on Mac OS 10.3.8 I'm trying to create artwork for a flex circuit layout, & vendor wants gerber file but says he can import DXF file. He is using CAM350, and says the software give "invalid file format error" or to that effect with my DXF file. tried both binary and text dxf versions, 2004, 2000, 14, nothing works. I forwarded the file to a friend who has Autocad2000, he says it opens fine, then creates a new DXF (from my DXF) from AC2000, vender says this file is okay. ??? Later, experimenting, I tried to import DXF into a freeware version of Cadstar, also got "invalid file format" errors, tried every possible DXF setting. Any help please?
