kashif		 I wanted to know about the term Chordal tolerance which we find in Points on Curve options in NX.? View All
While using the points on curve in Unigraphics for generating surface curves we come across the option of Chordal Tolerance . In that context i wanted to know the meaning of this term.

 Lets you space the set of points based on a chordal tolerance. The points are created from the curve start to the curve end. The value you enter in the Chordal Tolerance field represents the maximum distance between the parent curve and the straight line (chord) between two adjacent points in the set. Since the value is a maximum, any value less than or equal to the entered value can result.

The Chordal Tolerance spacing method works fairly well on arcs or circles with only 1 or 2 chordal distances less than the entered value. But on splines with large curvature variations, many chordal distances will be much less than the entered value (see figure from the website)

see if you could visit to the following website
