I think that you are correct with the 'Paste special' mode.
This has caught me in the past as well.
The way you have set up the planes should work fine.
I always only design '1-up'. I let the manufacturer create the panel array
to suit themselves using their Gerber CAM software. If I want a partic
Hello Luo,
Yes, you should use planes. I have found no bug here.
A possibility, have a look under, 'Design', 'Layer Stack Manager'.
Check that you have assigned your nets to the planes correctly.

Greetings all,
I may have missed some of this thread, but I wished to jump in to agree that
the proprietary interests of the software companies is a major setback to
progress on a good replacement for gerber format data.
I know several "CAM" operators that love odb++ and the Valor "Genesis"

That pretty much the same thing he said 8 years
ago. I've had some board houses tell me that they
love Valor's ODB++ and they are pushing the format
as the new standard.
A improved standard to replace Gerber would be great
but you need the various vendors to drop their
self-interest in their own

GenCAM did look much less subject to misinterpretation because of
the improved format. GenCAM capabilities looked very impressive
at the IPC Workshop but, if the PCB Manufacturers don't have GenCAM
what's the point?

If I recall correctly the IPC-D-350 was supposed to be a format that would
allow any CAD package to exchange data (in fact whole designs) with any
other CAD package. Talk about Utopia! It never caught on or hasn't

The IPC needs more teeth to be truly our guiding force. Most will agree

one point to consider here. Yes the new standards may be more robust

However Gerber has been around for decades in it's varied and different

to a degree you are correct but I don't see where they make any
serious money from adaptation of their standards. The moneys derived from

It was Dieter Bergman I was talking about at a IPC Workshop April 2001.
He also said (I'm paraphrasing) All of the PCB Designers need to apply
pressure on the PCB Manufacturers to start accepting GenCAM which is far
superior and will give us much better PCBs. Garbage in - garbage out.

I seem to recall attending a seminar back in 1993
where Dieter Bergman of the IPC was frustrated that
the industry had not stopped using Gerber when the
IPC-D-350 that he had personally helped developed
was "far Superior". I believe that GenCAM is the
direct descendant of IPC-D-350.

Brad,
Unfortunately it has been my experience that IPC = Dollars. Maybe they
have a vested interest and just want another thing to charge for.
That's my take anyway.

there are various formats a couple of IPC initiatives, ODB++, Gemcam, oh

I would like to write one cautionary note about the DDB file system: Back
up your DDB's often.
Of course, you should be doing this with all your filesbut we all know
that already ;)

them that I know of. Be prepared
Brad,
this sounds similar to an error I got on BOMs once. I found that it
went away after restarting Protel but not by just reloading the database. I
just put it down to some system glitch since I have never seen it more then
one or twice. Not much help if you have already tried restarting
Jeff,

external to the database. They will be generated within the database and you
can have them automatically exported to an external directory at any

Hi Rich,
you're correct in a way, controlling the arcs seems more problematic
in drawing polygon boundaries. The space key seems to work but then the
actual draw a curve segment doesn't seem to work, you can only draw a
straight line segment with absolutely no curve. Kinda makes some sense

was running.
