Chord length of a curve
WebOct 28, 2008 · If you use a 330 radius with a curve length of 164.41 you will end up with an arc turning right with a chord length of 162.715 that is tangent to the end of the line. If you use a -330 radius, the curve will turn left with the same dimensions. Peter Funk Autodesk, Inc.

The chord function is defined geometrically as shown in the picture. The chord of an angle is the length of the chord between two points on a unit circle separated by that central angle. The angle θ is taken in the positive sense and must lie in the interval 0 < θ ≤ π (radian measure). See more A chord of a circle is a straight line segment whose endpoints both lie on a circular arc. If a chord were to be extended infinitely on both directions into a line, the object is a secant line.
