<DIV>While we're talking about eagle, I've still got a few pressing
questions. I've got some nice schematics drawn up (like the ARP 4035
ladder filter module) and believe I'm ready to being making a board. And
here the process comes to a screeching halt. I've now made several
attempts, but really can't get anything remotly exceptable. Should I try
to lay down traces for the supplies and ground first? why don't the
icons for supply show up as something on the board screen? I'm using the
freeware version so I don't have the autorouter, is this worth the
money?<BR><SPAN class=009480701-08092005><FONT face=Arial color=#0000ff

<DIV><SPAN class=009480701-08092005><FONT face=Arial color=#0000ff size=2>The
autorouter is not worth the money IMHO. Looking at the board i'm working
on, it would be very unlikely if the autorouter did something like this all
by itself. it's an algorithm, it can't replace common
sense.</FONT></SPAN></DIV>

think you should lay down ground and power first. you can use the
command line and type commands like "show gnd" or "show vcc" to highlight the
airwires you need to lay down. if you're doing a 4 layer board,
draw polygons in the gnd/vcc layer first and don't mark the layers
as power supply layers because this gives you less freedom (don't name
them $gnd or $vcc). </FONT></SPAN><SPAN

polygons so they are connected to the appropriate net. </FONT></SPAN></DIV>

still impressed with Eagle, i am finishing my PCB in probably 1/2 the time it
took me with Protel, and this design is more complicated.</FONT></SPAN></DIV>
