Post OBO facebook fan Kirk Holfeld,

I got a question. When I create a new file I make sure that the units are set to inches but when I save it and then close it and re open later it is set to unitless. This becomes a problem when I send the .dxf files to a machine shop for a piece to be cut but they have no idea what the dimensions are suppose to be. Do you know how to fix this? Thanks in advance!
