I use Capture CIS (9.2 <-- yeah, I know I'm behind). If I'm going to make
the short on a component layer, I found a quick way to do it is to draw a
0-ohm resistor between the two nets. The resistor's assigned footprint is
just a very short wire segment. Solves all your DRC problems because you
have a component isolating the two nets still, even though fab produces a
short. The obvious drawbacks being that you have to place the short
separately from the tracks because the autorouter sees it as a component and
not a track, it can only go on component layers, and it violates some
notions of readability. On the up side it is very easy to do and very quick
to implement.
Thanks for all your help in the past Jim.

Hey folks. Hopefully a simple question. Does Allegro 15.1 now have the
ability to short two nets together without creating a DRC error? I want
to short a digital ground plane with another isolated plane, but they
both have separate net names. I know I can do it by adding a feature
that will short the nets together using a non-etch layer during artwork
extraction, but that will cause an error at the fab end. Isn't there a
property I can add to a shape or via or pin?
Thanx in advance

Sam,
Your English is fine. Welcome to the group. HillBilly is my second
language.
:-))) Does anyone have a Latin translation for HillBilly?

Subject: [PCB_FORUM] strange characters in gerbers
Group,
I'm using the 15.2 cadence, and I'm generating gerbers. I'm seeing extra
characters in gerbers, but are not visible when I dislay the fab
drawing. I've
enable all layers and don't see these characters. Any ideas?
Please excuse my unsophisticated english.
Sam
