Drawing circles inside circles

  Hi,
  
  In sketch mode, when drawing a circle within two larger circles, the surface between them is lost and seemingly no way to draw a circle and get that surface.
  
  For example, draw 3 circles one inside of the other - large to small.
  
  You end up with an outer ring, and an inner circle, but the middle ring has no surface. Trying to draw further circles to 'fill' the blank ring does not work, the only way to get a surface on it is to extrude one of the others first.
  
  In this example I am trying to work on the inner ring first, I want to extrude that (the bit it has not put a surface on) to leave an outer ring, and an inner circle both flat.
  
  How do I get it to fill/surface the bit it's excluding?
  
  Thanks

  Hi Sam Whitney
  
  You will have to create the middle circle again to get the surface for that and then you can extrude that keeping other surfaces flat.
  
  Please check the attached video demonstrating the process for you. Let me know if you have any further questions on it.
  
  Regards.

  Thanks for the reply Devendra, sorry I did not see the notification until just now.
  
  When I draw the new circle, it does not fill in the surface, no matter how many I draw (your last one) the inner ring is 'empty'.

    Please try turning on ''Enable Constraint based sketching option''.

    Devendra Badgujar I had that originally but found it really cumbersome for me, so I turned it off and it makes SpaceClaim much easier to use as I tend to draw on and faces.

  Hello Devendra Badgujar
  
  Isn't it possible by changing an option to be able to draw like in the old versions of SpaceClaim? I am attaching a video as an example.
