If I need to save a part from a design in the libraries I follow this procedure:
1) PADS Layout: Save Part type and PCB-Decal.
This will add the parttype and PCB-Decal to the libraries.
2) PADS Logic: Save Part type (overwrite existing parttype)
This will add the schematic symbol links.
My question wasn't totally clear.
The parts were already set up in the Library and were good. In Layout I added various attributes including Geometry.Height attribute for the parts in question. Looked good in Layout. I saved them to the Library so they would have that data for the next design. That's when it killed the link to the schematic gate symbols.
I'm guessing it's because Layout doesn't load the Schematic CAE Decals (Symbols). That makes sense, but when the part is updated in the library it should change only the items in Layout or added Attributes. It shouldn't delete the links to the Schematic Decals.
I'll have to try Menu: File / Library from PADS Layout and edit the library part.
PADS 9.3.1 ... I wonder if that is the case with PADS VX.2.1 ...
This has not changed - as far as I know.
