[SOLVED] Updating all footprints in Altium from footprints library without displacing components on PCB

[HighTechPower]

Hi guys. I'm designing a simple 2 layers PCB. I have routed the board. Now due to some issues & to make sure that PCB is updated with latest changes done in footprint library, I used the command 'Update PCB with All' and though it updated, a new issue rise up. I mean it displaced some components from their current routed locations. Any idea how to update PCB with all footprints and still avoid displacing the components from their current locations?

Actually I was performing a procedure given in link Making two assembly layers to define two assembly layers, top & bottom and this happened. you can watch this link from 21:30 onwards up to 25:50.

Updating library will not change placement position, except component origin was changed in the library.

Updating library will not change placement position, except component origin was changed in the library.

Yes I changed the origin of some footprints from center position to pin 1 once (I don't remember exactly for which footprints I did that). But now how to tackle the issue if I don't revoke the origin to earlier state.

I updated components origin (from center to pin 1) in library from another project and then replaced footprint library from that project to the current project, otherwise there was no change done in that as both libraries were identical.

However, I remember that then I "Updated PCB with All" footprints before routing the board and this displacement issue should not be appeared.

Or, is there some other efficient way to make two assembly layers, top & bottom without displacing components?

Yet another relevant question that can PCB manufacturers distinguish in top & bottom side of assembly if I keep single assembly file in case the mentioned issue is not resolved?

The components are placed relative to their origin. If you move the origin, the component will move, there's no way around it

Thank you FvM & barry, I reset the origins & issue solved for most of footprints, however as some components with same footprints had references at pin 1 and some at origin so I had the only choice to readjust others manually.
