and if you need something to run from a command line or shell find GZIP or an old copy of PKZIP.

And everybody misses the point..
You can export your dxf as 'ENTITIES ONLY'. There is a check box in the save as dxf dialog. It lets you select what should go in the dxf. It makes the file a lot smaller. Make sure you explode and purge any blocks first.

Does this make any real difference if you want to select all the drawing? I've just tried it and got 293,697 bytes standard dxf save 292,750 bytes select objects dxf save ????

Hi, You can try to save it DXF binary format. To do this type in dxfout. On the dailog box select >TOOLS>OPTION>DXF OPTION>BINARY
The output dxf file is much smaller and stable. Good Luck

The question is, will the cnc machine be able to read binary DXFs.
If I had a cnc machine that reads DXF and I can't get the filesize below a certain limit, I think I would try and load the cnc data directly, maybe that is more compact. Maybe not. Worth a try I guess.

That;'s a good plan.
I would also suggest to try different DXF version. Also, set all properties to BYLAYER so you don't store them in each entity (assuming you have got a lot of entities).
Slash, what version DXF does the cnc machine read? Would you send me a sample per emaill (get rid of the space in the address), I am more than happy to play with it for a bit.
hth, Jake

You've lost me now. What picture? Is that like a thumbnail? If that is so, you can randomly erase a few entities.

ok, do you have a new picture for each new cnc program? or do you have categories of profiles and and what you need is a picture for each category?
Say you have 200 cnc programs. How many pictures will you have? Does the picture show what is going to be cut?
Write in Dutch if it's easier. I'll make some sense out of it.
