Hey Mark,
Yes, all new changes will be incorporated every time. Use it all the time.
Good luck and duck those flying components.

Hello Pattie,
Ahhh...yup! Hate it.
We have been instructed to use "repackage" so it will pick up all new changes
and create updated packager files. Does "preserve" pick up all new
changes...every time?
Because of this "hate to see parts blown away" thing, we resort to hard
locating everything. We just can not afford the hit and this seems to work
fine, except we have the pain of hard locating in the schematic as mentioned
earlier.
Thanks for your feedback though. I will keep that in mind.

Hey Mark,
In Concept under File>Export Physical, in the Package Option area, click
Preserve. That will retain your reference designators during re-packaging.
Don't you just hate to see all your components fly off the board after a
schematic change?

Kevin,
We always hard locate ref des in Concept because we had been told that
if you do not, Cadence can change the ref des while re-packaging at a
later time.
This "soft location thing" never made any sense to us.
If anyone from Cadence is out there, can you explain WHY reference
designator are not always HARD LOCATED. This is done if you assign
designators in the schematic manually. We especially have to do this on
multi sectioned gates / components to ensure all sections package into
one IC.
And...while I am at it, it allows you to define duplicate designators
which then fails the packager.
Kevin, if you have all ref des soft located...you have never ran across
any unexpected ref des changes in Allegro?
I have been warned of this many times. To the point that I always hard
locate.
I would love to find out the rhyme or reason behind this.
Regards,
Mark

I know this isn't an answer, but why do you want the
locations to be hard. I've found them to cause
me grief over the centuries. Maybe I can still learn
a thing or two.
Oh, and I don't think there is a better way. Maybe a setting
that makes it put them on as hard. And on your 2nd question,
I think you need to package to get the refdes's, don't you?

When allowing Concept to assign ref des.
We are still doing the old,
find $LOCATION on each page.
Change "group" A
Ctrl E
find / replace $LOCATION with LOCATION
save text file
save schematic page
There should definitely be a better way!
Also, is there a file (prior to packaging to Allegro) that lists all
ref des used?
We usually package, then run a component report to see.
Thanks,
Mark
