Keep Out Area - between two circles - Autorouter

Hello, I need to create a "keep out" area for the autorouter. Normally this is done creating a solid region as "cutout". But how can I create such a solid region between two circles? ![image.png](//image.easyeda.com/pullimage/zHrGUbBX1FEqAtqvd2KHlawRWDMYye2PBf70cGwu.png) regards

You could use a solid region set to Solid ( or maybe No Solid) and set to a unique  net name. Note that if you use Solid Area set to Cutout, that creates a hole in the PCB. In either case you may need to delete the region after you have completed and checked the PCB.

@andyfierman but how to create a "band" (marked area, area between the two circles) of solid region? Seems to be impossible ... ![image.png](//image.easyeda.com/pullimage/ET1SAVNTDBYlCWliBWkAbsgLjA1mUJGVsU1lg7Oo.png)

You want to be able to autoroute in the area inside the inner circle and in the area outside the outer circle but not in the marked annulus?

@andyfierman only in the inner circle and exclude the region marked ...

So what's happening outside the outer circle?

Try this? 1. Define a circular Board Outline of the diameter of the outer circle; 2. Draw a Circle of the inner diameter then right-click > Convert to Solid Region;  3. Then set it to No Solid and assign it a unique net name;  4. Copy it onto the bottom layer;  5. Then place your components inside it; 6. Run the Autorouter.

@andyfierman Thank you. I tried to do as you mentioned but without success. I will try again with a more simple layout and will post my result here in the next days.

@MiniMax, I'm still not sure that I have the right picture in my head of what you want to achieve. Any chance of uploading a sketch to clarify?
