I've got two rather complex Altium projects, each consisting of multiple *.SchDoc and one *.PcbDoc. So far each of them has been developed idependantly but now they need to be combined into one PCB (Altium project). Is there a proper way of doing that without loosing schematic (designator, classes, directives) and layout (placment, tracks, polygons)? I don't see copying as the way to go. Somebody have suggestions for me?
Probably you want to combine them just for PCB fabrication.
Leave the schematics alone and make a new PCB with copy & paste.
You need to use "paste special" or the identifiers and net names are lost.
Note that LOCKED components are not copied. I consider that a major bug.
If you really want to merge the schematics, be sure to annotate them
that they have disjunct part identifiers and update the sub-boards.
cheers, Gerhard
