Where is the simple and efficient Circle option in defining the boundary of a detailed view?

Click, click, click, click, click, click, click, click, click, click, click, click, click, ... REDO! Need more clicks in order to make the boundary line smooth.
Is there an alternative to the mainstream "circle" selection in CREO? Most of the time, we only need a circle to focus and zoom into details.
Thanks.

p.s. If there is "circle selection" for defining the boundary of a detailed view, we will never use again the "Spline selection". (CREO's possible response: R U threatening CREO? We love Spline! In order to make you love and use Spline, we will never give you "circle selection" option!)
Thanks.
