I'm trying to get a sign done from a waterjet cutting place but they're asking for .ai, .eps, .dwg types or a CAD file. I'm not completely dumb with computers and have used GIMP and Adobe a little bit but I have no clue what they're talking about. I assume it's the 3d dimensional drawing that requires a special program? Is this something I can do? Can anyone help a brewer out?
Those are files done in programs like Adobe Illustrator, Cored Draw, AutoCAD, etc. If the drawing is not too complicated I could hook you up with whatever you need. Or you could download a trial version of Illustrator and play around with it.
The difference is that a raster format records what color each pixel should be while a vector format includes directions (vectors) for lines and colors. This means that vector formats can be scaled up and down.
GIMP does have more tools - since you need more tools to adjust drawings in a raster format. Think about inkscape more as a tool to assemble shapes - the intersction tools are extremely powerful.
