If you're manually annotating your schematics, then I'm not sure how effective the "Complete Existing Packages" option is. If the parts are already linked to separate PCB components then even resetting them and re-annotating them might not get what you want, which is why I suggested it might be easier to delete and re-add one of them. Effectively you draw multiple schematics (each counted as one sheet) and then you have one top-level sheet that connects them all together. ![]() ![]() The symbol represents the sheet below, and the sheet entries in it represent/connect to the ports on the sheet. If you had a bunch of the same part all with reset designators then it might pick two other instances to make a complete package, but should still try to make complete packages across schematic sheets. A hierarchical design within Altium can be defined as a design where the sheet-to-sheet relationships (the structure) in the design is represented, with sheet symbols representing the lower sheets in the design hierarchy. If you reset just those two designators, and then annotate the schematic with "Complete Existing Packages" set to "Whole Project" it should see that those parts can be fit into one physical package and annotate them that way (as long as one is A and one is B). ![]() Yes, if the designators are already set then Altium won't annotate them and won't assign them to the same package. In Altium there are different forms of interfaces possible between schematic sheets (individual signals,ports, harness).
