Premise: I work in integrated flow with a CL, PADS VX.
Let's say... I want to preserve an already done layout design, but at the same time I need to change the pin numbering of a component, for example, a diode.
In the past, for Diodes it was, like, Anode on pin 1 and Cathode on pin 2.
Let's say that now I want to change it: I want Cathode on pin 1 and Anode on pin 2.
Ok, then: I go to the symbol editor and swap the pin 1 with pin 2.
And then I go in the decal editor and swap the pad number, like I just did for the symbol.
So now my decal and symbol are aligned again. I go to the schematic and update the part.
Now I want to sync the layout.
Why the forward annotation delete my traces associated to that diode? Is there a way to avoid this?
