hello dear friends,
   i am working on a project of transforming the drawing.
I want to read the AutoCAD file in to VB program so that i can generate an equivalent drawing with the same co-ordinates. 
For this i need to know the file format of AutoCAD drawing file which contains the co-ordinates of the lines,circles.etc( shapes). I want to learn initial and end positions of this shapes.
"How i can read the file of AutocAD with extension( .DWG ) into my VB program to get the exact values of the drawing objectsn( lines etc ) 


Please help me in this regard with your valuable knowledge and experience. 

Best Regards,

If you do a "save as" in a DXF file format won't that contain the information you need?

There is a program out here called  "NC AUTO CODE" I can't find a new version of it. that writes M&G codes from autocad the last time I used it was in autocad 13 (not autocad 2013) it also worked in 2000i but I never up graded to it for use in 2000i and lost track of who now supports it but it was by Kramer Consulting, Inc. There seems to be a lot of companies with the same name. I know this is not much to go on but you may do some research and find help on this.
I am setting up my old system to check if I can take a dxf file back to AutoCad 13 and run NAC on it. I will let you know.

thank you for all. I want to learn it and if I can find that your program I wıll try it too. I wıll search it too here. 
NC AUTO CODE I wish it will help me. but if I can develop a vb code ıt can be better maybe. so I am searchıng a lıttle source code. I want to read dxf ıncredıents. I dont want to draw shapes with usıng vba. I saw it has book but my search is what is dxf formats. when I open it with notepad it has Line ... spline commands. and I wıll try to wrıte a apporiate code for it.
