I need to let the map zoom into a free-draw polygon’s buffer; the buffer can be 10 – 100 miles defined by the users, the buffer value is defined as BufferDistance.


I know for a circle with buffer, it can be defined such as   

var circleBuffer = new Circle(centerPoint, {



And then the map extent is set as:;

I test this circle statement, it can zoom into the circle buffer very well.


My question is: what if I want to zoom into a free-draw polygon with buffer? How do I get the extent of this polygon with buffer (not just polygon itself)?  In esri/geometry domain, a polygon constructor does not include any optional parameter like radius/buffer. I tried the following:;

It can only zoom into the polygon itself, not the polygon buffer. Thanks!
