It is possible to cut directly from Corel with some cutters....particularly Rolands. I have no idea if it will work with a Gerber. However it is far easier, in my opinion, to use a cutting program along with Corel. I have both of the programs you mentioned on different computers and either works well. If you're on a budget, CoCut will probably be the way to go. If you search through the old threads on this board there are a lot of them dealing with the subject of cutting directly from Corel and the various other software people use to cut vinyl. Lots of good information if you look for it.
