Found a 3d horse file and after much work I was able to convert each piece to a *.dxf file format and cut it on the laser.
This particular file was very troublesome, (and very large like 300in x 500 in ,it was probably metric )i have done many of these but it was never a lot of editting as this was.
Its not perfect but ok.
I like these files, i like the 3d to 2d and back to 3d
Used aspire after i was able to get the file format to *.dxfhttp://youtu.be/1LX_7Zx0pJQ
