ART (ArtCAM model)

ART is the file format of ArtCAM, a 3D modeling program from Autodesk which has been discontinued since July 7, 2018. Its format doesn't seem to be documented online. Various sites claim to have downloads of files of this format, but they all seem to either be for pay or at least with a registration wall, so there's nothing easily findable to examine the format. Early versions of ArtCAM actually required a proprietary dongle in your computer to even open the files.
