Re: gEDA-user: Locking down auto-routed traces?

["harry eaton" <bumpelo@comcast.net>]

My version doesn't seem to add any blobs. While I have a work-in-progress
version that's not in CVS yet, there is nothing in the code that I think
would affect this. My guess is that the current CVS version doesn't create
such blobs. It's also curious that the blobs in your example file DON'T have
the AUTOFLAG set, indicating that they weren't created by the autorouter.

Any chance these were created by the "trace optimizer?"

I don't recommend manually futzing with any internal pcb flags, which is to
say I don't think you should follow Dan's suggestion. Instead simply use the
:RipUp(Selected) facility to only rip-up the targeted nets and/or lock them.
