It becomes a problem of renumbering  the designators on the different boards to
have
a unique number and for these numbers to match with the schematic designators.
This then allows full DRC.

I do this renumbering stuff on most of my schematics and boards and the best way
I have found is to use an addon server that can be downloaded from
www.qualecad.com.
 It allows you to either add a suffix to the designator ie R1 -> R1_X    or to
add an offset
ie R1 -> R301.

Subject:  [PEDA] Stepping up



Hi all,

I have a project with 3 small (about 8 sq inch) PCBS.

A set of PCBS for a unit consists of 2 of one type and one each of the
others.

Volume is low and my board house makes fixed charges for plotting and
screen set ups which represents a fair part of the cost for say a batch of
10 sets.

One of the PCBS really needs to be 4 layers, 4 layers would be nice on the
others.

I am thinking of making a panel with a set of 4 PCBS on it whch to the
board house looks like one plot/screen charge and a bit of extra routing.

Any thoughts on the best way to do this?

I am a bit worried about just copying into a new PCB file. There is
obviously no valid netlsit for the set and I am worried about plane
connections which are automatically derived from the netlist - is there a
danger these will be lost or screwed up? I don't need annotations so
component renaming is probably not an issue.

At the moment I am thinking of merging gerbers with Camtastic but not sure
what problems I will run into.

Any advice?


Cheers, Terry.
