Hello Eagle community, wondering if there is a clever way to do logical operations on artwork, e.g. I'd like to create an annulus by removing part of a circle? Thank you.Logical

I believe you can do it on the top or bottom copper layers, but not any
inner layers.
Try adding a circle to the top copper layer for the outer diameter.
Then add a circle for the inner diameter on the tRestrict layer. You
could do this in the package editor in a library and treat the ring as a
device that could be translated or mirrored to the bottom.

On any layer just draw a circle, specifying the width. Hey presto!
instant annulus.

Chuck, thanks, What I am trying to is create a circular ground-plane for a monopole antenna, with the feed coming in through the top metal also. So, I need the keep-out to be in the center of the ground-plane for the monopole soldering hole, as well as keep-out for the (microstrip) trace. From your suggestion, using the tRestrict layer, does that instruct Eagle to not place metal in the shape of the object on tRestrict, or do I need to merge these layers?
Thanks.
Thanks.
