I'm sure it's possible, but I suspect it would be more complex than what I
suggested, unless a truly large number of components were involved. There
would be a lot of work massaging the text files, giving each section the
proper offset and component designator increment, and then running place.
This also requires the parts for the first section to be placed and the
other sections to be absent. Not difficult, just one more complication.
The simplest way I know to do offset repeat sections is, when creating the
first schematic section, to use a section prefix and constant refdes
suffixes. I.e., prefix all parts with an x, say, and number each part
within its section as 01, 02, 03, etc. So the first section might have
resistors Rx01, Rx02, etc., capacitors Cx01, Cx02, etc., etc. The first
section should be saved separately as a scratch schematic.
Then one copies the block as many times as necessary. By selecting each
block and globally editing it with a match criterion of "selected," the x
can be changed to 1, 2, 3 etc. I think paste special or the annotation tool
can do this kind of thing directly, but, again, I'm short on time today.
On a PCB, parts from the scratch schematic would be placed and routed, then
selected and copied to the clipboard. Then they can be edited to the prefix
for section 1, unselected and the next section pasted and similarly edited
to the prefix for section two, etc. Each selection when pasted will be
selected and ready for unique edit. Then the net list would be loaded and
primitives updated.
But what I wrote earlier was a method of stepping sections when the
schematic had already been numbered, perhaps automatically, and one did not
want to change it, for whatever reason.
Nevertheless, Mr. Wilson's suggestion would work, I would think, and it
might even be better.
Any of these methods would be faster than hand-copying each section, unless
they were very simple and very few copies were being made.
