Hi @robertferanec , this is another big 'flaw' in Altium Designer the way I see it, if you cannot change the reference designators to any arbitrary values in a design, by importing the information from an outside source file. (What it was, and what you want it to be for each component.) Or can you? If you could, that would make my day...
Theoretically you could do it using Delphi scripting, but Altium R&D doesn't seem to have updated the scripting API since Altium 6 as far as I could find out. You can do scripting, I tried it myself, it just doesn't work.
We do have this requirement most of the time a board is hand-assembled and the way I attempted it is that I use a PADS Layout version to come up with the changes, then I copy-paste the table in sections to PCB List reference designators and then match up schematics to PCB in Altium.
Sometimes it works, especially if there are not a lot of parts...
If I want it to work for sure, I do it in PADS Layout, but then it is a nightmare to match up the schematics... Luckily most of these PCBs have OrCAD schematics, and this is not a problem with
OrCAD.
