Checks the position, tangent, and curvature continuity between curves.
The Curve curvature tool prints messages in the prompt line about the continuity at the intersection you clicked:
The curves are not exactly curvature continuous,
but are still within the tolerance set in Preferences > Construction Options 
. <deviation> is
the difference in curvatures at the intersection.
The curves are not curvature continuous. <deviation> is the difference in curvatures at the intersection.
The
curves are not exactly tangent continuous, but are still within
the tolerance set in Preferences > Construction Options . <angle> is
the angle between the curves tangents at the intersection.
The curves are not tangent continuous. <angle> is the angle between the curves tangents at the intersection.
You did not click a point where two curves (and only two curves) intersect.
The initial scale of the lines which show the tangents of the two curves. The actual length of the lines is proportional to the angle times this scaling value.
You can change this value
when you use the tool by holding 
and dragging the

Creates a persistent locator that displays the continuity between curves (that is, the locator remains even after the Curve Continuity tool is no longer active). This allows you to monitor curve continuity as you edit curves.
The locator appears only as a green circle (the curves are continuous) or a red circle (the curves are not continuous).
The locator indicates whether the position, tangents, or curvature of the curve are continuous.
