It seems many people are unaware of this tip. Eagle does not have a button to allow you to fully unroute after you have routed your board. If you wanted to start routing again, this would be nice to have. Moreover, the following tip allows you to undo all your wire routing with one command.
As an example, lets take the Wiznet WizFi Wifi Booster Pack board:
Say, I want to unroute the whole thing in one go. Go to the command section in Eagle on the top left and enter – ripup; That is correct, pretty explicit 🙂
You should see the following:
How awesome is that! If you like this tip, say hello below or you could also share more tips.
Or:
Click the Ripup icon then click Go. ;o)
Whoops! Total fail on our part then 🙂 Thanks xMob.
I realize it’s an old thread, but when you rip it up, it doesn’t restart the autorouter, that I can tell. I set the autorouter to a single side board. They reverted back and I cannot change them. Now it produces double sided boards. 🙁 I’d like to just start it over. Thanks
You can also do: rip *
I use “ripup GND” when I have a polygon named GND as my fill. I’ll ripup GND and then make some changes to the other wires, then hit the autoroute to fill GND back in.
Thanks!
How about this one: how do you undo a poly fill after you have executed the ‘rats’ command. Never found that out – for years I have ran ‘rats’ to take a look at how things are and then to resume editing had to click on a side of a ground fill, resize (this removes the fill) then Ctrl-Z to undo the polygon resize. A bit roundabout to accomplish the task. Am I missing an obvious command somewhere? Wish there was an unrats or cats (rats are afraid of cats) or star (rats backwards?) command.
What I do is close the board window, go to schematic and press the board button again. You should see all your polygons unrouted.
See my comment above. Whatever you name your polygon fill, type in the command line: “ripup POLYNAME”. Ratsnest to fill in again.
It does not work. If you are also defined some GND vias then they are also ripped up.
1. ripup GND
2. and then undo ctrl+z
There must be better solution for that.
under options,settings, misc unclick ratsnest processes polygons. or type SET POLYGON_RATSNEST OFF;
now when you run ratsnest it wont auto fill polys.
but aha you say what if i want to fill them in.
assign a key, to this macro
SET POLYGON_RATSNEST ON;ra;SET POLYGON_RATSNEST OFF;
Thanks!!!
I knew there had to be a way. Thanks for publishing this, and thanks to the commenters for the additional info.
