Mechanical question

Hi,
Does anybody know, how to find out values of attributes from ACMBALLOON?

Kari

 

(setq entobj (vlax-ename->vla-object (car (entsel))))

;returns - #<VLA-OBJECT IMcadBalloon 0b20a914>
;the balloon object

(vlax-get-property entobj "bomitems")

;returns - #<VLA-OBJECT IMcadBOMItems 0b1bf2b4>
;the items collection for the balloon

(setq obj (vlax-invoke-method bomitemlist 'item 0))

;returns - #<VLA-OBJECT IMcadBOMItem 0b1bda14>
;the item for this balloon

(vlax-safearray->list (vlax-variant-value (vlax-get-property obj "data")))

;returns - (("MASS" "0.382186") ("DESCR" "EYE BOLT, 1/4-20") ("NAME"
"080-00201"))
;the value list for that balloon
;(vlax-get-property obj "data") returns a variant
;(vlax-variant-value... returns a safearray
;(vlax-safearray->list... converts safearray to list


Hope that's enough to get you going.

Have fun,
Dave

 

I have had a little problems with these newsgroups, so I answer after 2
weeks of original message....

I have got this error message:

error: no function definition: VLAX-ENAME->VLA-OBJECT

There is something wrong with this line:

(setq obj (vlax-invoke-method bomitemlist 'item 0))

On versions of AutoCAD prior to 2004 you need to call (vl-load-com) at least
once per session to have those functions loaded. It does not hurt to put
that statement at the top of any function that uses the (vl*) functions.

Before you can use any vla-* or vlax-* functions, you must
call (vl-load-com) at least once.

That's the case on all versions of AutoCAD, including 2004.

 

My vanilla profile for A2k4 (no customization FIAK) runs vla/vlax- functions
fine.

Yea but aren't you the same guy who thought
that (entsel 123) doesn't throw an error?
(probably because you had a global *error*
handler loaded, which you didn't know about).

Found it. Something in the Express Tools for A2k4 loads it. My apologies to
Kari for the misleading statement about A2k4 loading it automatically.

Actually I had to add that vl-load-com (I saw one example in
afralisp-sites). I have found out it by myself couple days ago, when I got
error-message earlier.

There is still something wrong in (setq obj (vlax-invoke-method bomitemlist
'item 0))-line....
