There are dozens of free vector mockups and vector bird models (pigeons, storks, owls, swans) for laser and plotter cutting, engraving and cutting out in DXF, CDR, EPS formats. The models can be used as ready-made vectors for ArtCam and other programs for creating models to work with milling machines and CNC lasers.
DXF files can be imported into ArtCam and easily opened in CorelDRAW and other vector programs.
EPS files open directly in ArtCam.
DXF files are in fact text files that contain vector coordinates - by importing them into ArtCam you can edit them in that program.
