I am building a library for Altium Designer version 15.0 and have a schematic component as well as a PCB footprint. The footprint is linked to the schematic through the dialog opened when I double-click the component in the schematic library and add the footprint there. If I then edit the footprint later on, do I need to re-add it to the component through the schematic library, or is it updated automatically? I'm leaning towards the latter but want to be certain.
I have been continuing my work on the libraries and it appears that it does NOT update automatically. Perhaps there is some configuration somewhere, but it looks like the default requires you to remove the old footprint and re-add the updated one.
Two why to doing this:
1-go to your PCB component library and select : TOOLS >> Update PCB with ll Footprints, which change all PCB that used this library in any project !!!
like this :
2- Save the new PCB component library with new name, In Schematic of those project go to:
TOOLS >> Footprint manager then select all component which you want to change it's footprint PCB library and in right part select edit option and change those component footprint then select Validate >> Accept Changes (Create ECO)
