Autodesk Suing to Keep Format Closed
An anonymous reader writes "AutoCAD is by far the industry standard CAD tool for engineering drawings. When I was an engineering student it was on every computer in the college of engineering. Autodesk, the makers of the AutoCAD software, are attempting to quash an effort to reverse-engineer the proprietary binary format used by AutoCAD. Looking at the court order, their whole argument revolves around something called TrustedDWG that basically looks like a digital signature that verifies the file was created by an Autodesk product."
There was a recent discussion about this case, and the central point was NOT that the open source group was reverse engineering documents. It was about the open software's representation of itself as a "genuine" file using the AutoCAD name. The equivalent to a ODT file containing the terminology "Genuine Microsoft Word file, guaranteed to work". I have my issues with Autodesk, but they aren't necessarily the evil ones here.
Right, and that combined with their products only working with signed drawings means they're using this watermark as a ruse to try to monopolize their corner of the industry. This is basically what HP and Lexmark have tried to do, in which they've put code in their printers to check the manufacturer of the printhead. There's no reason for it technologically, it's only there for anticompetitive purposes. Same here, and the DMCA, as bad as it is, does say that using copyright as a ruse to prevent interoperability won't fly.
"On the other hand, well . . . who gives a shit?"
.dwg file that is not "trusted" into AutoCAD and a dialog pops up with warnings that say the file format is not "trusted, unsafe, etc".
Well, for one, the end users do, when they bring in a
Extending your GM analogy, say you install a non GM part in your GM car and get a blinking light on the dash to the effect of "Car may crash violently or explode through use on non-GM part." What are the results of that? The consumer is scared back into going to GM and GM only to buy the part.

The best analogy I can think of is GM saying you can only put 'genuine GM' parts in their cars.
Actually, a better analogy is GM making their oil filters in the shape of the GM logo. If you make an oil filter that fits in a GM, you have to make it in the shape of their logo, thereby violating their trademark.
