vlax-curve-get Error

[Jonathan Handojo]

Hi all,

 

I seem to stumble into a little problem here...

 

This image below is returned from a "Break On Error", and the error message returned is "Error: bad argument value: AcDbCurve 667". My function JH:selset-to-list is the equivalent to LM:ss->ent in Selection Set to List. I inspected the variable 'cr' and it returns an entity name. (And for some reason I can't open the watch window). I really now don't know what else is the issue. Does anyone ever encounter this problem? Sometimes the program works and sometimes it doesn't.

 

 

 

 

Thanks,

Jonathan Handojo

Just a stab do you need the and the objects do have a start and end point property so get ss then do say repeat and make the list of  points.

Post the drawing where this error is happening.

It's crashing on a PolyFaceMesh object:

Is that a lisp that is outputting the dxf group? I have Dumpit  but its displays vla object data not dxf groups

 

;;----------------------------------------------------------------------------;;
;; Dump all methods and properties for selected objects               
(defun C:DumpIt (/ ent)
  (while (setq ent (entsel))
    (vlax-Dump-Object (vlax-Ename->Vla-Object (car ent)))
  )
  (princ)
)

That info came from the Vlide 'break on error' then print results. I use this to see DXF items:

(defun c:dxflist (/ e)
  (cond	((setq e (car (entsel "\nPick something to see DXF data: ")))
	 (mapcar 'print (entget e '("*")))
	 (textscr)
	)
  )
  (princ)
)

 

There is also DUMPALLPROPERTIES to be used in conjunction with get\setpropertyvalue
