I’ve exported my designs to DXF files to get them machined out of Carbon Fiber. The vendor says the files are reading in inches not mm. From what I’ve found the DXF files are dimensionless and THEY would have to tell their importing app what dimensions to use so that I get a part that’s 146mm across not 146" across (big piece of CF) Is that true or is there some way I need to tell 123Design how to export correctly?
