matrix cadHello .I want to convert CAD file or simple file (created by lines , circle or such these structures) text fil

I want to convert CAD file to a file as matrix structure .so I need a plotter driver that makes a this file.
I will change the file data by own software to plot the main CAD file using my Plotter that I makes it myself.
I hope that the file creates by the driver convert a line to a two points and some commands thenmatrix cad I change this to my structure.
For example convert a circle by the dimension of : center of circle =x ,y radius=r to : c=x ,y R=r or such these formats
I think that the first pen plotters works as above an so if I have a these driver I can archive to my goal
Tanks for your help.

I tmatrix cadhink the file format you are looking for that describes graphics as vectors is DXF. Most CAD programs can output DXF files and there are free downloads that will convert PDF files to DXF.
DXF files are quite big and you will have to filter out what you don't want but they are easy to see what each line is doing.
