Capture reference designators swap

Lock2002
Lock2002 over 5 years ago

I have a preliminary component placement that I'm pretty far along with when an engineer decided to change all reference designators on the schematic. I'm not sure if they made other net or comp value changes before doing this. How should I go about fixing this? 

Thanks

    Hi Lock, in capture I used both tool's annotate to reset the ref-dez to ? then re annotated again. I also changed references manually and both ways worked fine. The footprints on the board got updated to the new references. Now if I changed a footprint type in the schematic to a new type then that footprint would get ripped off the existing board which is to be expected. By way of an example if C1 was a 0805 resistor and I changed C1 to a 1206 type then the 0805 for C1 would get removed from the board.

    Maybe you can verify in capture that your placed board "Input Board" & "Output board" are the same and that "Place Changed Components if same is checked" under netlisting.

    A very easy way to confirm things is just do a simple schematic with say 3 symbols and create a board based on those first. then go back into capture and change your input board and output board to be the same, using your newly created board as the input board.

    Next either manually change the re-dez or annotate etc.. It does not matter. Upon netlisting again you should see that the references update fine without problem.

    If parts are getting ripped off the board it sounds to me like that actual footprint got changed on the schematic.
