To Create a User-Defined Analysis
 |
Before creating a UDA, you must create a Construction group.
|
1. Under Model Tree, select your own references and create a group LOCAL_GROUP.
2. Click > . The User-Defined Analysis dialog box opens.
3. Under References, accept the default references used by the feature.
4. Under Calculation Settings, specify the following:
◦ Parameter—Select the analysis feature parameter you want to compute.
◦ Domain—Specify where to perform calculations by choosing an option. Select Selected Point, and then select one or more points on the domain where you want to perform the calculation.
▪ Select Entire Field (default) to perform the calculation on the entire domain where the field point is located, for example, the entire surface.
5. Under Computation Settings, define the resolution by clicking the appropriate icon:
◦ 
—Define the resolution by setting the density of points. The default density is low. To increase the quality, you can increase the density to high.
—Define the resolution by setting the density of points. The default density is low. To increase the quality, you can increase the density to high.◦ 
—Define the resolution by setting the exact number of points.
—Define the resolution by setting the exact number of points.◦ 
—Define the resolution by setting the distance between two adjacent points in the model units.
—Define the resolution by setting the distance between two adjacent points in the model units.6. Min/Max Refinement—Obtain more accurate results for the minimum and maximum values without increasing the density or accuracy. This option is available only for the Entire Field domain.
◦ Create Graph—Show results in a graph window.
◦ Dynamic Update—Creo Parametric updates the results automatically. You need not choose Compute to update.
7. Under Results, click:
◦ Settings—Set the scale and density of the display and specify calculation options. For UDAs with the field point on an edge or curve, you can set the scale and density. If the field point references a surface or a quilt, you can set increment (linear, logarithmic, or two-color), spectrum (upper and lower limits, and sensitivity), and accuracy (low, medium, high, or very high). Choose OK to close the dialog box.
◦ Compute—Generate the results of the analysis. The results appear in the box under Results. The results of a UDA can be a porcupine display accompanied by a graph (if the field is a curve or an edge) or a shaded display (if the domain is a surface or a quilt).
◦ Clear—Erase the display of the results.
8. 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.
9. Click Close.
