Part Two
Creating a printed circuit board
Back annotating
The Back Annotate command creates a file with a .SWP extension and puts it in the
same folder your board is in. You then read the .SWP file into Capture in order to
update the schematic that corresponds to your board with any changes you made to
the board while it was in Layout.
&
See For information on reading a .SWP file into Capture, see the Capture
documentation.
If you create a .SWP file and then run Back Annotate again, Layout prompts you to
save your board file, to keep your board file synchronized with your .SWP file.
M
Caution You must read your .SWP file into Capture before creating another.
Otherwise, the next back annotation overwrites what had been in the .SWP file.
This means that your board and the schematic will become unsynchronized and
you will not be able to resynchronize them.
