To Display the Dihedral Angle for an Edge or Curve
A dihedral angle is an angle between the normals of the two surfaces that share an edge.
1. Click Analysis. From Inspect Geometry, select Dihedral Angle. The Dihedral Angle Analysis dialog box opens. Quick is the default analysis type. The Analysis tab is selected by default.
2. Click in the Edge collector and select an edge, point, or datum point on an edge for dihedral angle analysis. The name of the selected entities are displayed in the Edge collector.
The minimum and maximum dihedral angles are displayed in the result area at the bottom of the dialog box and an angle plot 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 a new edge 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 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. Click to display the analysis result in a separate window. The Chart-Tool window opens and the result of analysis with the parameter values for the selected curve or edge is represented graphically in the Chart-Tool window.
6. Optionally, to customize or edit your analysis, perform the following steps:
a. Select the Quality, Number, or Step type of sampling in the Sample box. Quality is selected by default. Adjust the sample values using the slider or thumbwheel.
b. Adjust the scale of plot using the thumbwheel. The selected value is displayed in the Scale box. You can also adjust the scale graphically using the handle on the curve or edge of a surface.
c. Select the required plotting style.
d. 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.
