DXF fields

[alijahed]

Hi All,

 

I am so happy posting something here after a long time. I've learned lots out of this Forum since I joined in 2007. Thanks for being helpful during these years...

 

Today I have a question regarding reading a very simple DXF file drawing a LINE from (20,20) to (817,20).

I can spot the information about the POINTS (Start & Finish) in the body of DXF file but I don't understand the other bits and pieces in the body of DXF file.

 

Can someone please explain what is what and to do what?

 

Cheers

Ali

Google "object dxf code autocad"

 

Replace object with say line, arc, cicle and so on , also look for entmake examples.

Also use this on a line or anything in a drawing to see its DXF codes.

;----------------------------------------------------------------------------;;
;; Dump all DXF Group Data             
(defun c:DumpIt (/ SS)
  (if (setq SS (ssget))
    (foreach ent (vl-remove-if 'listp (mapcar 'cadr (ssnamex ss)))
      (mapcar 'print (entget ent '( "*")))
      (textscr)
    )
  )
  (princ)
)

My $0.05 

 

(entget (car (entsel))) its short enough that I just type it on command line.

 

I prefer dumpit to be for Vl properties.

    (vlax-Dump-Object 
      (vlax-Ename->Vla-Object (car ent)) 
    ) 
  ) 
  (princ) 
)
