exporting a modified symbol out

Hello Masa,  Allegro keeps a copy of the symbol definition with the database. A modified symbol(moving pin or Text location etc) is a symbol instance and when dumping the
libraries Allegro dumps the symbol definitions only. 


Therefore .a modified symbol is a symbol instance and when dumping the libraries Allegro dumps the symbol definitions.

Modified padstack definitions can be exported, but not pin location changes.

Hi Masa,

I believe that when you modify a padstack in Allegro or APD and then use File > Export > Libraries

you are exporting the modified padstack data

thank u for response.

well, i wonder why i can export the modified padstack but not the original padstack which is a padstack before the modification.

in the same token, how come i can export the original symbol but not the modified symbol?

how are the padstack and symbol treated differently while they r exported out?

Hi Masa,

When you load a symbol into allegro/APD it loads the data into a SYMDEF object type, the placed symbols are copies of that data

When you modify a symbol in a design layout you are changing the copied data, not the original data loaded from a symbol file

thank u for ur reply, david.

is there a way to export the copied data?

maybe exporting as a sub-drawing?
