being too expensive, I kept searching and found something that claims to

be a free cost autorouter, but you have to run it over a website, no

downloads. Anyone else tried it and have comments?

don't know why someone told you to avoid EAGLE autorouter, nothing wrong

with it.

you do see a lot of comments on these forums saying NOT to avoid MANUAL

routing, but that is not the same thing. No autorouter can fully replace

manual routing on critical circuits. And many simple boards are just as

easy to do manually as auto.

What might be useful is a new tutorial block in the EAGLE documentation

on advanced autorouter usage and general advice on how to route a board.

Meaning, route any tracks with special requirements by hand first, set

autorouter to drop vias as Jorge recommends, routing power traces only

and using classes, why/how to set routing grid ( VFAQ ), what do various

router passes try to accomplish ( I think this is already in there, at

least  a little ), how to customize router settings to get the board you

want ( what each setting does ), what tasks are typically part of clean

up, when and how to use more passes as Olin has indicated he uses a lot.

Any other ideas what could be included?

Well. Autorouter is very limitied, I mean not "eagle" but to make a good

layout with high speed, low EMC, meet all rules to meet for CE. Well I use

autorouter juste if the board is for a test or have no speed no CPU.

I have try "Freerouting" because you can push & drawing a new trace, it is

very usefull and I dream to have it in Eagle on day.

But I have not quite "understand" or found the way to use it. Some time, I

can not route a net, some time it's move all trace, make some "funy" angle.

Well it is using to much time to use for a good layout.

But if someone has use it, please tell me what I have not understand.
