Example: Analyzing the Cross Section of a Nozzle
Summary—This example shows you how to create a User Defined Analysis (UDA) to investigate how a model parameter changes along a trajectory.
Problem—Need to analyze how the cross-section of a solid pipe changes along its trajectory.
Solution—You can create an analysis feature to compute the cross-section at a point on the curve and create a UDA to analyze the cross-section along the entire curve.
Follow these steps to create the UDA:
1. Create a field point on the trajectory curve and click > > .
2. Create a datum plane through the field point.
3. Create an analysis feature to measure the cross-section of the nozzle.
4. Click > . The Cross Section Properties dialog box opens.
5. Click the Analysis tab if it is not selected by default and select the type of analysis.
6. Click Save to display and dynamically update the analysis while modeling.
7. Enter a name for the analysis, for example, nozzle_area.
8. Click the Definition tab to customize or edit your analysis.
9. Under Cross Section, select a cross-section name or select the reference datum plane in the Plane collector.
10. Under Coordinate System, the selected coordinate system is displayed in the collector. Click Use default to select the default coordinate system.
11. Click 
to compute the analysis. A coordinate system is displayed at the center of gravity of the cross-section in the Creo Parametric graphics window. The result of the analysis is displayed in the Results box and the report is displayed in an information window.

15. Click Compute from the User Defined Analysis dialogue box.
16. To save this analysis in an analysis feature, click Add Feature and enter the name for the feature. A new analysis feature appears on the Model Tree.
17. Click Close.
