Editing dxf files

CraigP

If I open and edit a dxf then hit save I do not want to be prompted to "Save Drawing As" a dwg file.
I just want to save the dxf.
Changing the default Save format is not an option as we work with both dwg and dxf daily.
Is there an option/setting that I am not aware of?
cheers

You could achieve this using some LISP. The function below will switch the SaveFormat automatically as you switch between drawings.

; SetSaveFormat
; Sets the save format to match the current drawing extension

(defun SetSaveFormat ( / ext)
    (setq ext (strcase (acet-filename-extension  (getvar 'DWGNAME)))) ; retrieve the current drawing file extension
        (cond ((= ".DXF" ext)
                        (setvar 'SaveFormat 5) ; If drawing is DXF, set saveformat to 2013 .DXF
                        (princ "\nSave format set to .DXF")
                    )
                    (T (setvar 'SaveFormat 4) ; Otherwise set saveformat to 2013 .DWG
                         (princ "\nSave format set to .DWG")    
                    ) 
        )
    (prin1)
)

; Set a reactor to call SetSaveFormat each time the current drawing is changed
(vlr-docmanager-reactor nil '((:vlr-documentBecameCurrent . SetSaveFormat)))

(SetSaveFormat) ; auto run on loading

To use, you would either include in your on_doc_load.lsp, or set to load automatically with APPLOAD.

Thanks Jason, this is exactly what I was looking for.

Hi Jason
It might be something on my system but if I save an open DWG as a DXF you would think that SSF would then save it as DXF next save - but it doesn't. SSF is auto loaded at the start of each session and does give the right save settings for DXFs and DWGs that are open, but after I save a DWG as a DXF it persists in trying to save as a DWG subsequently. This is unfortunate because that is exactly how my work flow goes - I draw my parts in DWG, then purge all non-essential elements to produce a clean DXF for CNC - this DXF might be tweaked and re-saved several times before it's finalised. SSF seems to ignore its new file type though.
If I close the DXF then open it, then save again it silently saves as it a DXF.
Cheers

Update the LISP to include a check when the drawing file is saved.

; SetSaveFormat
; Sets the save format to match the current drawing extension

(defun SetSaveFormat ( / ext)
	(setq ext (strcase (acet-filename-extension  (getvar 'DWGNAME)))) ; retrieve the current drawing file extension
		(cond ((= ".DXF" ext)
						(setvar 'SaveFormat 5) ; If drawing is DXF, set saveformat to 2013 .DXF
						(princ "\nSave format set to .DXF\n")
					)
					(T (setvar 'SaveFormat 4) ; Otherwise set saveformat to 2013 .DWG
						 (princ "\nSave format set to .DWG\n")	
					) 
		)
	(prin1)
)

; Set a reactor to call SetSaveFormat each time the current drawing is changed
(vlr-docmanager-reactor nil '((:vlr-documentBecameCurrent . SetSaveFormat)))

; Set a reactor to call SetSaveFormt each time the drawing is saved
(vlr-editor-reactor nil '((:vlr-saveComplete . SetSaveFormat)))


(SetSaveFormat) ; auto run on loading
