  DXF file parsing in POV? (Message 1 to 9 of 9)

Hi. I'm wondering if this is possible.I've spent a some time trying with no 
success. I'm trying to extract the position of POINT objects from the DXF.
The file will look like this (note: comments were added for clarity, they 
are not in actual DXF file):

  0
SECTION
  2
ENTITIES
  0
POINT           // start of point object
  8
DEFAULT
  5
1E
 10
9.99498             // x coord
 20
9.993288             // y coord
 30
0.045681             // z coord
  0
POINT
  8
DEFAULT
  5
1F
 10
9.983854
 20
etc, etc.

TIA for any help or other feedback.

Dave.

POV-Ray has no internal support for .dxf files but many conversion programs
exist that will convert from dxf2pov. 3DWin and Crossroads for example -

Sorry, I wasn't clear enough in my original post. Using the file i/o 
commands(fopen, read, etc) I want to read in the float values for a POINT 
objects position and apply it to a POV objects translation.

Thanks, Dave.

The file i/o function require that values are separated by commas
(whitespace doesn't count) and strings are enclosed in double quotes.
If you convert your DXF file to obey these rules, you'll be able to
read it into POV.

Thanks for your help. If I have to write a converter I'll just extract the 
coordinates at that point and write them to a suitable file.

If you are using a UNIX (this includes Linux), it's rather easy to add the
commas and the quotes with the proper sed-command.

):5;i&&_>1;printf("%s",_-70?_&1?"[]":" ":(_=0,"\n")),_/=2);} /*- Warp -*/

Just out of curiosity, what are you reading them in for?

	Kindof defeats the original aim of "DXF file parsing"
	if you have to massage the data....

I wanted to get a curve from Rhino into POV that I could put objects along. 
I had ditched the idea of parsing in POV and wrote a C program to convert the 
DXF to a comma delimited file with the coordinates.
