Problem with changing the value of an attribute

[Anonymous]

Im changing the value of an attribute this way (progn (setq el2 (subst (cons 1 ts1) (assoc 1 el2) el2)) (entmod el2) (entupd (cdar el2))) Sometimes it works an somtimes not. Can someone tell me why? The result of subst is okay but entmod and entupd doesn't seem te have affect on it. MJ

You are likely mixing ActiveX and vanilla AutoLISP (in A2k2 and earlier, have not verified in A2k4/5). Search a few years back in this ng on this topic for more details. -- R.

Try:
(progn
(entmod (setq el2 (subst (cons 1 ts1) (assoc 1 el2) el2)))
(entupd el2)
)

Marcel,

give the following change a chance:

(progn (setq el2 (subst (cons 1 ts1) (assoc 1 el2) el2)) (entmod el2)
(entupd (cdr (assoc -1 el2))))

Same problem here. Such an old thread I imagine there was a solution somewhere...

I would switch to the newer (setpropertyvalue) world [which didn't exist when this topic began], in which the Tag of an Attribute constitutes a "property" of the Block insertion:

(setpropertyvalue BlockEntityName "TagName" "NewValue")
