Sometimes I have to output a .drw file into something our packaging designers can use in Adobe Illustrator. They use it to create dielines to trim labels and cards in their packages. It might for example be a card that in 3D folds in a package. I flatten it in Sheet Metal, do a drawing of the flat pattern and output the file for the packaging people.
I usually export to dxf, and the entities come out as splines with control points. Trouble is when they import these files into Illustrator they often invert the control points, so what looks like a spline from a distance is actually looping back on itself, like a string with big thumbknots tied in it. So if this entity is used in our vinyl cutter (like a printer except it cuts vinyl) it tends to get very confused. Anyone had this kind of problem? We use to export the drawing to iges, then import it into Autocad 14, then save it to dxf. (AC 14 was the last release to translate between iges and dxf or dwg.) Now I can't install 14 on Vista, and anyway there must be a more sensible option. Illustrator also takes pdf, but I'm pretty sure we're getting the same problem there.
