Looking at DXF to GRAY? Here's why GRAY isn't a standard "save as" target — and what to use.
GRAY isn't a normal image format — it's a headerless raw pixel buffer, so there's no meaningful "convert DXF to GRAY".
A GRAY file is just a stream of raw pixel values (grayscale samples) with no width, height or color information stored inside. Anything opening it has to be told the exact dimensions and layout separately — so it isn't a portable image you can simply convert to.
For an image you can actually open and share, pick a standard format that stores its own dimensions and color — SVG, PDF or EPS.
DXF is an open CAD interchange format nearly every CAD program reads — common for CNC and laser cutting.
How to open DXF opens in virtually all CAD software plus CNC and laser tools.
