How to convert c++ output into AutoCAD dwg or dxf File

[sunithbabu78]

hello,

i have written a C++ program which gives an output as circle =

circle(10 10 25)

point (10,10)

radius = 25

now the graphics output should also generate an DXF or dwg file which can be opened in AutoCAD any version [2000 above]

thanks .............

I'm not all that familiar with C++ but couldn't you change your program to have an output that is compatable with lisp? If you just change a little bit of the formatting, your output could very easily be a lisp routine.

Well, I'm not an expert, but I believe that the format for what you want to do would be

(defun c:test ()
  (command "circle" "10,10" 25)
)

In place of the word "test" put what you would like to enter at the command line to invoke the lisp routine.

Sunith,

I'm not a Mod so i can't move this to the appropriate forum, but if you post the same question in the Programming/Autolisp forum you'll get better results.

There are some great minds in there just dying to solve problems like yours.

Hope this helps.

I would just like to second what Ken said.
The lisp routine I posted is extremely basic and limited. If you want more than drawing the specific circle you described definitely go to the Programming/Autolisp forum.

your program need to put this text data to a file with a ext of *.dxf
the number after the 8 is the layer name
the number after the 10 is the x
the number after the 20 is the y
the number after the 30 is the z
the number after the 40 is the radius

to put more then one circle repret the code start at

Circle

to

for each circle

how this file can be inserted or open with autocad

Your c++ program need to open a file and write the code as show I have not done much c++ programing and can not help with the code. but the step are

1. open the file
2. write the data to the file
3. close then file
4. open or insert the file in AutoCAD

note:
write this to start the file
this code tell AutoCAD that the data to come is data for entities

0
SECTION
  2
ENTITIES

write this code for each circle you need
replace the 6.0 with the x of the center of the circle
replace the 4.0 with the y of the center of the circle
replace the 0.0 with the z of the center of the circle
replace the 2.0 with the radius of the circle

 
 0
CIRCLE
8
0
10
6.0
 20
4.0
 30
0.0
40
2.0

end by write this to the file and close
this code tell autocad that is as come to the end of the ENTITIES SECTION
and to the end of the file
