This may be an easy question, but it is causing us fits. We are using DxDesigner VX.1 and Pads Layout VX.1.
We recently had a board almost completely finished and ready for a final review. As librarian, I modified the silkscreen on an IC so that the Pin1 marker was a label and not a graphic (so we can move it in the layout). When my board designer did a forward annotation to update the library, the IC was ripped up along with all the routed tracks and was left with a rat's nest.
Why? Nothing changed in the part that would require a reroute. We've tried gluing the part and protecting all routes. Neither works. There has got to be a way to do this without losing a day's work everytime.
BTW, we are new to PADS.
