OOOUUUCHHH! That hurts, 100+pours?
I wouldn't even want to imagine trying to manage the pours on that
board. I have to assume you are doing some form of power circuitry from your
comments. Not my forte but I have done some.
Yes I would be looking to get those pours down in number, they just
become more of a management issue than most people can handle (not to mention
can Protel handle them?). I would limit myself depending on how they were
defined. I know it is time consuming to pour detailed pour outlines verses just
a general block/rectangle but I would think that detailed pour outlines is the
only way for you to go. Then even if you have 50 pours or more, at least they
are not a management problem because you know precisely where their outlines
are supposed to be because you located those outlines precisely. That is the
manner in which I did power designs previously, you have to know where those
pours are located and that they are not order dependant through 30 or 40 layers
of repour ordering just to repour one polygon.
I would also look at why you can't just use wide/fat traces for a lot
of your signals as well. Then where they connect and you rely on multiple
spokes of a pour for the connection, do the same with smaller traces. Just make
sure you have the Option for Remove loops turned off or it will remove your
multiple traces as you edit.
If you draw detailed polygon outlines try to work out a grid system
that allows you to draw them quickly considering spacing and your outline
requirements.

Brad,
Looks like you've got me on the right path. This is a two layer
board with 100+ pours as I need to maximize copper area for grounds,
power, and higher current traces. It would be very tedious to route
all these pours by hand.
Any suggestions? I'm thinking about limiting pours as much as
possible. Maybe get down to 5-10. Do you think I'll have better luck?
Thanks again,
Steve
