To Display the Curvature of a Curve or Edge
1. Click Analysis > Curvature. The Curvature dialog box opens. Quick is the default analysis type.
2. Click in the Geometry collector and select one or more curves or edges for the analysis. The name of the selected entity is displayed in the Geometry collector.
The minimum and maximum curvature of the selected curve or edge is computed. The result is displayed in the result area at the bottom of the Curvature dialog box. A curvature plot for the selected curve or edge is displayed in the Creo Parametric graphics window.
 
* To clear the contents of the collector, right-click in the collector and click Remove on the shortcut menu. You can then continue to select new entities in the collector to create a new analysis.
3. Click OK to complete the analysis or Cancel to cancel the analysis.  Alternatively, click Repeat to start a new analysis.
4. Optionally, to save the analysis or create an analysis feature, perform the following steps.
a. Click the Analysis tab if it is not selected by default.
b. Select the desired analysis types from the list at the bottom of the Curvature dialog box.
c. Select Saved to save the analysis with the model, and to display and dynamically update the analysis while modeling or select Feature to create analysis feature.
d. If required, rename the analysis in the box adjacent to the list.
e. Click the Feature tab to change feature options of the current analysis, if required. You can access the feature options only when you select a feature type of analysis.
5. Optionally, click to display the analysis result in a separate window. The Graphtool window opens and the result of the analysis with the parameter values for the selected curve is graphically represented in the Graphtool window.
6. Optionally, to customize or edit your analysis, perform the following steps:
a. Select Curvature, Radius, or Tangent type of plot in the Plot box. Curvature is the default.
Curvature—Evaluates and plots the curvature along the selected curves or edges. For a single surface, evaluates and plots the curvature of surface in both the directions as isolines.
Radius—Evaluates and plots the radius along the selected curves and edges.
Tangent—Evaluates and plots the tangents along the selected curves and edges.
 
* You cannot create a new feature for analysis with a Tangent plot.
b. Select the Quality, Number, or Step type of sampling in the Sample box. Quality is the default. Adjust the sample values using the thumbwheel or slider.
 
* The number of samples must be greater than 1 and the incremental value for the step must be greater than 0.001 in model units.
c. Adjust the scale of plot using the thumbwheel or type a value in the Scale box. You can also adjust the scale graphically using the handle on the curve or edge.
d. Select the required plotting style.
e. Update is selected by default. You can see the effects of your selections or changes on the analysis plot as you make them. Clear the Update check box to select or adjust multiple analysis options, and click Preview to view the result of the analysis.
