VP Layers - 2002 vs 2004

Has the method of storing viewport frozen layers changed from 2002 to 2004?
I have a routine I wrote in for copying frozen vp layers in 2002 that
another user cannot get to work in 2004. I've tried everything I can think
of without having 2004 to try it on.

In 2002, I could save the layers frozen in a viewport by getting the (assoc
341) of the VP entity. This no longer seems to be the case. Can someone
verify/debunk this? If it's verified, what might I use to get this info.?

Thanks,
Jeff

 

Russ,

Here's a link to the 2k4 dxf code list. It shows 331 containing the frozen
layer data--now I'd like to know WHO had that brain fart. I mean what's the
purpose of changing something like that? ;-)

All versions of the code list are available from here:

It does seem strange that they have changed that.
I've always used the xdata for the viewport regardless.
It returns layer names rather than layer entities, which
IMO is more directly useful.

(entget (car(entsel))(list "acad"))

RDI,
It's Jeff, not Russ....but that's OK. I answer to just about
anything......;-)

Thanks for the link. I'd searched for that, and knew it existed because I've
been there before, but just didn't find it for some reason.

If they didn't change things like this, how would we ever get errors in our
code????? ;-)

Thanks for this tip, Doug.

I have used this in the past and now I don't remember why I didn't continue
using it.....aren't there other things that save data under "ACAD" using the
1003 code?

Well I'll modify my code to use this and see what happens....

Thanks again,
Jeff

 

Sorry about that "Russ" er Jeff.

I had just read one of "Kiwi Russ's" posts a few minutes before.
