Vla-explode with NUS block fails - bug in 2k4/5?

Hi all

Has anyone recognized this new 'feature' in 2k4/5?
There was never a problem in 2k2 with the explode method.
_$ (vla-Explode (vlax-ename->vla-object (car (entsel))))

Is EXPLMODE sysvar set to 0? Needs to be 1 to explode NUS blocks.....

 

NUS?
Non-uniform scaled?

 

Hi Jeff

EXPLMODE is set to 1...

Cheers

 

Yep..

Cheers

 

Juerg,
Thanks for noticing this 'bug'. That really limits the application
of vla-explode. Back to command methods. ;-(

Hi Doug

Unfortunately yes... meanwhile I use this workaround:

Code:

(defun MeExplode (Obj / ExpObj ObjLst TmpEnt)
(setq TmpEnt (entlast)
ExpObj (vla-Copy Obj)
)
(if (vl-cmdf "_.EXPLODE" (vlax-vla-object->ename ExpObj))
(progn
(setq TmpEnt (handent (cdr (assoc 5 (entget TmpEnt)))))
(while (setq TmpEnt (entnext TmpEnt))
(setq ObjLst (cons (vlax-ename->vla-object TmpEnt) ObjLst))
)
)
(vla-Delete ExpObj)
)
(reverse ObjLst)
)

Cheers

 

Good workaround Juerg. Thanks for posting it.

Regards,
Doug

 

Hi Jürg,

Do a test of a block made of polylines... and see the difference.... if the
nus block is exploded.... the polylines turn into lines, but from a uniform
block they become polylines.

 

nus block is exploded.... the polylines turn into lines, but from a
uniform

as what the command is supposed to work... then to me and never had put
attention to this is also a bug... will try to make a test on 2000i

 

Welcome...¦-)

Cheers

 

Jürg:

Just watch out using (entlast). If the last object contained sub-objects like
vertices or attributes, then (entnext) will retrieve them...

(defun @cv_entlast ( / e elast)
(setq elast (entlast))
(while (and elast (setq e (entnext elast)))
(setq elast e)
)
elast
)

 

Hi John

Yesterday I ran also into this. Together with your function it works well.
Thank you...¦-)

Hi Luis

That's correct. But the explode methode shouldn't fail on NUS blocks.
This was working in A2k, A2ki and A2k2, but not in A2k4 and A2k5...>8-(

Cheers

 

You're quite welcome. I think I still owe you more than you owe me.
