Hi Matt,
I had tried those options. It may be, in my case, that if the footprint was
changed in physical size, say, from an 0402 to an 0603 and the new footprint
would create a DRC error and it won't place it. If DRC is why, then I could
turn DRC off and see.
Regards,
Austin

Under inport logic, ther is an option block for what to do with changed
components.
Pick always and changed components will be placed where they were, unless
the symbol or a padstack is not available.

Hi Trilok,When you say you changed JEDAC, do you mean the physical
symbol (PCB footprint)? If so, then it will do just as you say in my
experience. It only keeps placement of components that are the same
physical symbol (and REFDES). Unless there is an option somewhere that
prevents it from doing that, it's the way it works.The way to avoid this,
possibly, is to change the footprint manually by using "Logic/Part Logic"
and changing the "Allegro Packages" for the parts you want to
change.Regards,Austin

Hi Everyone,Here's a problem while importing Logic in allegro. Board
is completely routed & I am re-importing logic with minor changes, Some of
the components are disappearing from board & appears on the Menu -->
Place -->Manual --> Components by ref des.We have changed JEDAC only for
changed components. In Import logic, I have tried all possible options. This
problem is both in Allegro Designer & Expert. We use version 15.2 Has
anyone faced similar problem & got any remedy.Thanks in advance.Trilok
