Help is careve region

I'm working on a project where I have a rectangle that is set to a carve region depth of .4. Inside of that I need to create a ring that comes up .25 from the floor. I tried creating two circles (one inside the other) and setting the inner one to a carve region of .4 to match the rectangle and the other one to a carve region depth of .25 thus hopefully creating the ring I need. This did not work. I also tried additive and subtractive with no luck. Could someone please tell me how I can make this work?

Thanks!!!

It would help if you posted your project file to see what you have.

WOW! I really messed up the spelling on this post topic. Sorry about that.

Sorry. I am still using designer 2.xx so couldn't open your mpc. So hopefully close to what you had in the mpc. I used clip carving exclusive on the square/rectangle and then clip carving exclusive on the outer circle with the depth measurements you referenced. Maybe the graybeards have a better way of doing it.

Thanks oscarl48. That seems to work.
