I use Bobcad for this. I don't think you can actually make a "DXF to G-code converter". G-code describes moves of a cutting tool to CUT a part. DXF just describes the shape of the object, it doesn't even know what is the INSIDE and what is the OUTSIDE. I mean you could have a perfectly valid DXF drawing where there is no way to tell whether the outline given is a hole cut into a big block or a solid object. With Bobcad, there is the user to describe what is to be cut, and what order it should be done in. There is a cad package that is now bundled in with EMC2/Ubuntu, but I don't think it has G-code generation in it. I haven't tried it, yet.

Re: [Emc-users] Isel & Linux
Over the years, I have been watching for good Linux based CAD software and this one got by me. I have used LinuxCAD and now Synergy, and I mean no disrespect to them, but they seem to be a collection of powerful graphics routines brought together by a mediocre user interface. If I get time, I will need to investigate Graphite One to see if it is any better. I like qCAD, but it's limited to 2D drafting, but I find it fun when I can use it for what I am doing. The best CAD software I have used (though not Linux based) was CADAM (from IBM?). The software came with a keypad with buttons for drawing functions. Each button was lit when it became a valid input. You never had to guess what the next step was. I think, at the time, it cost something like $10k a seat (Oh, the good old days).

Re: [Emc-users] Isel & Linux
Hi Jerry, thanks a lot!!! I would not have found that on my own at all and I watch linux CAD systems constantly. What a nice find! I am sure going to try it out now. What I really like is the MILL instruction along a predefined route. That really simplifies things. You basically just route a path with line segments and then say mill alongh path after you give the bit size. That is quite nice!

[Emc-users] Isel & Linux
I studied up the G-code of my Isel Machines and is now ready to write a translator that can work with EMC pretty easily and finaly move everything over to Linux, by means of the intermediate translator I wrote. That part is sorted out. The remaining task is to replace the Windows Cad program. I am using BobCad at the moment on windows which is a truly *painful application* and overly complicated CAD program riddled with ambiguity and a workflow only the programmer understands. My question is, is there a simple 2-d 3-d cad program with DXF or such output I can feed into EMC for toolpath generation? A CAD program I REALLY like is "emachineshop" as it is at last a 2-d 3-d cad program anyone can understand. "http://www.emachineshop.com/audio/07-menu-job-order-help/video.html"; Unfortunately it does not export any DXF and such so you must use it to buy at emachineshop. Is there any CAD similar and as clear to use available on Linux? I just dont have the time and energy to fight through Autocad and even worse, LinuxCad to do something simple in 2-D. Emachineshop is about 100% a good match for what I am doing.
