Curve Utilities Toolbox

The Curve Utilities toolbox contains tools for converting elements to B-spline curves, and for creating, evaluating, or matching curve settings.

All tools in a toolbox are not always visible by default. To see all tools, right-click in the toolbox and select Show All from the menu.

To	Select in the Curve Utilities toolbox
Convert an element to a B-spline curve with the same shape.	Convert to B-spline Curve
Convert a B-spline curve to lines, a line string, a stream curve, arcs or points.	Facet Curve
Graphically and numerically evaluate the attributes of a B-spline curve at given locations on the curve.	Extract Points from Curve
Place a curve by defining its mathematical formula.	Curve by Formula
Match the active B-spline curve settings to the attributes of a B-spline curve.	Match Curve Settings

Key-in: DIALOG TOOLBOX CURVEUTIL

Key-in: ANALYZE CURVATURE POINT

Note: The ANALYZE CURVATURE POINT key-in can be used to analyze a curve at a point along the curve. When you activate the tool and select the curve a full circle displays at that point on the curve. As you move the point along the curve, the radius of the curve is displayed in the status bar. The u-value is displayed in the Message Center.
