Copy circuit from one board to another...?

Davyblues

I've been away from Allegro for three years and I'm trying to remember how to copy a circuit (parts, etch and planes) with intelligence from one board to another. I'd rather not put the circuit together manually using a clipped sub-drawing... I'm trying the plctxt commands and having problems. When I type "run plctxt_out" on the command line I get error "Run returned non-zero status =-127." When I type "run plctxt", it crashes Allegro. I am using 16.5 I know I've done this before...help remembering how?

    "run" would be expecting a script file, "plctxt" and "plctxt out" are "just" commands so you don't need the "run" on the command line. You can also use File>Export(Import)>Placement from the menu. (See the pcomms.pdf in the doc\pcomms directory of the installation) You are only going to get the placement in this case through, rather "all" the circuit. You could use Placement Edit Application mode and create a MDD file from the existing circuit, this can contain placed components and routing, you can then "apply" thsi to the new design and PCB Editor will match the RefDes's between the circuits. (Check the algroplace.pdf in the doc\algroplace directory of the installation for a discussion of Placement Edit Application mode)

    Remembering the tools in the menu is a... Thanks for the edit>export>placement (duh). Would have been nice if the help documentation about plctxt would have mentioned that as an option.

    The PDF documentation...what is the installation you are referring to and where do I find the paths to those documents (doc/pcomms and doc/algroplace)?

    That will lead me to the documentation about the Placement Edit Application. That sounds like the process I need to try.

    Thanks for your time...
