When I export an dxf file such as

import processing.dxf.*;//import DXF library

//8x11" in pixels
int width=8*72;
int height=11*72;

void setup() {
 size(width, height, P3D);//use P3D renderer for DXF
 noLoop();//draw only once
}

void draw() {
 beginRaw(DXF, "output.dxf");//start writing to file
 
 //begin drawing
 for(int i=0; i<10; i++){
   for(int j=0; j<10; j++){
   line(0, height/10*i+j*9, width/10*j, height/10*i+j*9);
   }
 }
 //end of drawing
 
 endRaw();//stop writing to file
}

and try to open the file in adobe illustrator cs3 (mac) it only shows up as text. I found a program that can view it, but it can't save the file in again as dxf so that I can open it in adobe illustrator. Does anyone know how to open exported dxf files in AI?

the problem with PDF is that I can not edit the individual lines to certain specifications so that the lazer cutter can read it.

such as 0.1 lines, and very specific colored lines such as 0,0,255 or 255,255,0

do you know a way so that exported pdf can maintain line/shape information

thanks.

Ive managed to open the DXF file after I saved it in rhino as a dxf again and then open it in adobe illustrator. (weird) That's the same case with my instructor. Though all the dxf file viewers I have manage to find either can't save as DXF and keep lines/shapes for AI, or it is only a trial with very limited saves.
