BENT lets you dimension an arc or circle whose center does
not appear on-screen. 

You can use BENT to dimension an arc or circle that you
have not autoscaled. You can tell that you are looking at
a bent radial dimension when you see part of an arc or
circle that extends off-screen, along with a dimension
with a leader line that zigzags.

Cursor select the arc or circle you want to dimension.

Cursor select the reference center of the arc or circle; 
this is the leader's start point.

Cursor select the leader line's first bend, or elbow.

Cursor select the leader line's second elbow. For a sharp
angle, select almost directly above or below the first
elbow.

Indicate the dimension text position using an option from
the Position Menu. Make sure that you place the text 
somewhere between the second elbow and the arc or circle.

CADKEY displays the dimension and its leader lines.  If
you make a mistake, choose UNDO in the Break Area or press
(Alt)-(I). CADKEY deletes the dimension and leader lines
and you can indicate another dimension text position.
