About an Analysis Feature
An analysis feature is a regular Creo Parametric datum feature that is used to capture a measurement. The analysis feature may contain a regular Creo Parametric analysis, user-defined analysis, or feature relation.
An analysis feature is composed of:
• A name
• A type (UDA, Relation, Excel, PTC Mathcad, Creo Simulate, or Motion)
• A definition (consisting of the measurement or analysis to be performed, the relations to be evaluated, or a UDA)
• Results of the analysis to be included in the feature
The results of an analysis feature can be one or more real or integer parameters containing the value of the measurements made within that feature. You can also create datum points, coordinate systems, or graphs as a result of analysis features. These parameters and datums can be used the same way as all Creo Parametric parameters and datums to drive subsequent features.
For example, you can create a parameter controlling a measurement of the mass of a part at the instance where the analysis feature occurs in the regeneration cycle. You can then place a coordinate system of the center of mass as measured at this point in the regeneration cycle. However, you cannot create an analysis feature with more than 125 parameters.

You can use the configuration option clearance_triangulation to improve the quality of the results of an Analysis feature. Setting this configuration option affects the quality of the initial guess for Newton's method, used in distance, clearance, and interference computations. Note that the improved quality of computations increases the analysis time.

You can capture results of an analysis in an analysis feature while still working with the ANALYSIS dialog box. After you compute the analysis, click Add Feature in the ANALYSIS dialog box and specify the name for the feature. The analysis feature appears on the Model Tree and updates whenever you regenerate the model.
