To Display the Curvature of a Surface
1. Click > 
Curvature. The Curvature dialog box opens. Quick is the default analysis type.
Curvature. The Curvature dialog box opens. Quick is the default analysis type.2. Click in the Geometry collector and select one or more surfaces or quilts on the object for analysis. The name of the selected entity is displayed in the Geometry collector.
The minimum and maximum curvature of the selected surface is computed and displayed in the result area at the bottom of the Curvature dialog box. A curvature plot for the surface 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 the reference geometry or coordinate system in the collector. |
3. Select Spacing in the Sample box and specify spacing between the mesh lines in the first and second direction. Alternately, click Number in the Sample box and specify the number of mesh lines in the first and second direction.
4. Click OK to complete the analysis or Cancel to cancel the analysis. Alternatively, click Repeat to start a new analysis.
5. Optionally, to save the analysis or create an analysis feature, perform the following steps:
a. Select the desired analysis types from the list at the bottom of the Curvature dialog box.
b. Select Saved to save the analysis with the model, and to display and dynamically update the analysis while modeling. You can select Feature to create analysis feature.
c. If required, rename the analysis in the box adjacent to the list.
6. Optionally, to customize or edit your analysis, perform the following steps:
a. Click in the CSYS collector and select a reference coordinate system.
b. Select a Curvature or Normal 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.
▪ Normal—Evaluates a single surface and plots the normals to surface in both the directions as isolines.
c. Select the Quality, Number, or Step type of sampling in the Sample box to plot the curvature in the first direction. Quality is the default. Adjust the sample values using the 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. |
d. Adjust the sample values for the 2nd Quality, 2nd Number, or 2nd Step type of sample plot and the scale in the second direction. These options are available based on the values selected in the Sample box.
e. 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.
f. Select the required plotting style.
| | You cannot specify a plotting style for the Normal type of plot. |
g. 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.
