Hello everyone,
Funny how many of us are fighting with the Same Problems. (not so funny when
you realize that Michael Schmitt and me are probably working on PCBs for the same
devices ;)
Like Brad (Mr. Valander) I have tried a lot of Rules to vermeiden this DRC-error. And
like him I did

Good point.

Thanks for the tip--but what is the 'hole size editor' and how do I run it? I don't
see it anywhere in the menus or help...??

No but try seeing how many holes the hole size editor reports and edit the
problem hole size setting it to the same size anyway.
The hole size editor has problems with holes that are almost the same
Has anyone seen this problem (Protel99SE, SP6):
I create the following 3 outputs from my PCB:
- Drill Drawing (.GD1) Gerber
- Drill Drawing 'Print Preview'
- Drill Report (.DRR) file
The 'Print Preview' drill .LEGEND table correctly shows that I have 1156 holes of
various sizes (14 tools, t

no seriously though i could see this as at least a potential cosmetic
issue for the fab
(not being able to hold the dimensions)
that could be enough to trigger a reject from the customer ...
why use these dimensions anyway?
you don't want a solid due t
I have not heard of that being a problem , but you could point out to
them the fact they have made this board twice now and why do that
consider it an issue this time?

I just had a board vendor reject my gerbers due to the track spacing within
a polygon pour. I have been using 15 mil tracks on a 20 mil grid and this
yields 5 mil track spacing, which violates the 8 mil track spacing minimum
this board vendor has.
Since all these tracks are shorted together anywa
Michael,
sorry, that rule doesn't work in the case of keepouts (general, or
layer specific). I use almost that exact rule already and you are right that
the deletion of the general board-board clearance rule presents a risk. Any
no net item can short to another net if the board-board clear
I know, I know, I know, how to do it
Create a class of nets to include all your nets, Delete the default board/
board clearance rule, add a clearance rule ( your net classname ) to ( your
net class name)
It works but I wouldnt use it, I was tinkering with this several months ago
while doing BG
Michael,
I have some very similar needs but have never found a way to
accomplish this task. I have had the same results as you have described. I
look forward to reading any results that have come to a different
conclusion.
In my case I have tried the exact same thing with layer spe
we run into this all the time
just don't think of the keep out as the board outline
we make the board outline on mech 1 or whatever and then draw the
keep out layer either on top of the board layer or inside the the board
layer a little bit
in your case you would just bend the keep out layer aro
Michael, I've handled this issue by offsetting the Keep Out tracks/arcs
outside the physical edge of the board by a fixed amount, say 10mils.
If the board is to have Polygons or Planes, you may have to create a
temporary set of keepouts to control polygon/plane pours to a wider
clearance; if these
Now to something completly different ...
I use Protel 99SE SP6 and i want to create / modify my design rules so that
there will be no drc errors if a pad and / or a track is touching the keep
out.
Imagine a pad placed inside the pcb-outline and keepout's but the outter
diameter of that pad is no
