Ratio is toggled ON, the Fit B-Spline Options box expands to display the following. Setting the Chord height ratio to a value greater than 0 results in more edit points being generated if the ratio on the curve is greater than the current Chord Ht. For example, the default value of 10.000 means that the height must be ten times the chord length before additional edit points are created. A lower value would result in more edit points being created. If a value of 0 is used, the Chord Ht.
Ratio is ignored.
In effect, this would be the same as toggling Chord Ht. To change a value, click in the field, type a new value and press Enter. The Chord Ht. Ratio and its associated tolerance options only applies to fitting surfaces and is not used for fitting curves. All rights reserved.
