Follow-me router settings

That's really silly, downright irresponsible if you design boards for

anyone else.

DRC is a important part of the board design process.  Especially when

manually routing, you want something that verifies you didn't put two

tracks too close together, copper too close to the board edge, maybe even

accidentally have two tracks cross, etc.

Also, you don't create a DRC.  There are always some DRC settings.  The

only question is whether they match your desired design rules or not.  Some

of these DRC settings aren't just for error checking either, they effect

the resulting copper.  Examples are thermals, minimum annulus, and lots of

others.  You are using some DRC settings all the time, whether you

explicitly set them or not.

Did you even look at the router settings?  There is such a thing as a

"hugging" parameter.

Since this was my first post to the forum I'm surprised by this

unfriendly tone. I think you actuallt misunderstood my question, after I

setup the clearance rules from the PCB manufacturer I want to use the

follow-me router when doing manual routing in such a way that the

artwork is not violating any rules (i.e. not causing any DRC errors).

This is achieved with the follow-me router since it doesn't allow the

artwork to cause DRCs errors, this is what I want by I'm looking for

good settings for the follow-me router. The default rules have cost

associated with all kinds of things such as steps and changing

directions. It's not obvious which mix of costs and routing grid works

best here.

Yes of course, along with the manual and the tutorial. I turned to this

forum for some best practice since this wasn't covered in any of these

documents.

Dont mind Olin. He has a long history of harshness to people that didnt
