Messages

The Curve curvature tool prints messages in the prompt line about the continuity at the intersection you clicked:

Curves are curvature continuous within tolerance - curvature deviation is (1/cm) <deviation>

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.

Curvature deviation between curves is (1/cm) <deviation>

The curves are not curvature continuous. <deviation> is the difference in curvatures at the intersection.

Curves are tangent vector continuous within tolerance - angle is (degrees) <angle>.

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.

Angle between the curves at their intersection is (deg) <angle>.

The curves are not tangent continuous. <angle> is the angle between the curves tangents at the intersection.

Select curve intersection.

You did not click a point where two curves (and only two curves) intersect.

Options

Tangency Scale

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.

Curvature Scale

The initial scale of the lines which show the curvature 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.

Locator Persistence

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that displays the continuity between curves (that is, the locator remains even after the Curve Continuity tool is no longer active).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.

Simple Display

The locator appears only as a green circle (the curves are continuous) or a red circle (the curves are not continuous).

Display

The locator indicates whether the curves' position, tangents, or curvature are continuous.
