To Display the Slope of a Surface

1. Click Analysis > Inspect Geometry >

Slope. The Slope dialog box opens. Quick is the default analysis type.

2. Click in the Surface collector and select one or more surfaces, quilts, solid geometry, or facets on which you want to perform surface analysis. The selected entities are displayed in the Surface collector.

3. Click in the Direction collector and select a reference plane, coordinate system, straight curve, edge, or axis. The Color Scale dialog box opens. You can flip the reference to reverse the direction indicated by the arrow on the model.

The slope is computed and the minimum and maximum slope values for each newly selected surface appear in the result area at the bottom of the Slope dialog box. A shaded plot for the selected 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 continue to select a required surface, model, or reference in the collector.

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 Saved from the list at the bottom of the Analysis tabbed page to dynamically update and display the analysis while modeling or click Feature to create analysis feature.

b. If required, rename the analysis in the box adjacent to the list.

c. 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.

6. Click

in the Color Scale dialog box to view the color scale options.

7. Click

and move the pointer over the colored model to display the slope value of a colored surface in a tooltip at the pointer location. As you move the pointer over the colored model an indicator moves along the color scale indicating corresponding slope value at the pointer location on the color scale.

8. Select one of the following types of styles for the selected surface or surfaces:

—Displays the color plot with a linear scale.

—Displays the color plot with a logarithmic scale.

The logarithmic type of plotting style is not available if both negative and positive shaded curvature values exist for the selected entities.

9. If required, click

to restore the default values of the color scheme.

10. Click

to switch between the continuous and non-continuous color display and customize the color plot by modifying the number of colors for a linear or logarithmic type of plotting style. For non-continuous color display you can specify the number of colors for the color scale in the Number box.

You can modify the minimum and maximum values for color gradation in the Color Scale dialog box for both continuous and non-continuous color display.

11. Optionally, to customize your color plot, click one of the following types of color plots in the Color Scale dialog box:

—A rainbow type of color plot is displayed for the selected surface or surfaces.

—A three-color type of color plot is displayed for the selected surface or surfaces.

You can modify the minimum and maximum values for color gradation in the Color Scale dialog box.

12. Click

in the Color Scale dialog box to save the color scheme settings to a .txt file. Clicking

opens the Save Color Scheme dialog box with color_scheme as the default filename in the File Name box. If required, specify a new name and click OK. By default the file is saved to the working directory.

To load a color scheme click

and browse to the.txt file that contains the color scheme settings.

13. Optionally, to customize or edit your analysis, perform the following steps:

a. Select the Quality, Number, or Step as the sampling type in the Sample list. Quality is selected by default. Adjust the sample values using the slider.

b. 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.
