Using Performance Reporting
You can analyze a part or assembly and understand which sub-models and features require the most regeneration time. General statistics on the model are available as well.
To view the performance report, follow these steps:
1. Open the Performance Report dialog box using one of the steps below:
◦ In any open model, click > > 
Performance Report.
Performance Report.◦ In an open assembly, click > > Performance Report.
Performance Report.The Performance Report dialog box opens. showing the Regeneration tab and the Statistics tab. Note that there is no regeneration data the first time the dialog box is opened.
2. To view the regeneration times, click Compute. The Full Regeneration Confirmation message opens.
3. Click OK. The regeneration times (in seconds) for each component and feature appear in the table. Regeneration times are listed for all features in a part and for all components, component placement, and features of an assembly. Click the arrow to the left of a part to see the features of the part.
◦ When you click Compute, all features in the model are fully regenerated. Depending on the model quality, there may be regeneration failures. Features that are read only and empty models are not regenerated.
◦ After a regeneration the components and features are sorted by the regeneration time.
◦ Miscellaneous represents regeneration related time which is not currently accounted for by specific objects. This node appears once under the top model and includes times related to the entire structure. When you open a sub-model in a separate window, the Miscellaneous node is empty until you click Compute.
◦ Other Items includes the regeneration times of the following items for each component: Relations, Pro/Program, Family Tables, Assembly Cuts, Flexible Components, and Mechanism.
◦ Suppressed and Excluded components are not included in the regeneration time.
4. To view a flat list of components and features, click Flat List. You can show the top-level components and features or all levels of components and features.
5. To view the assembly component information, click Statistics. A list of the different types of components in the assembly displays with the number of components for each type.
Suppressed and excluded components are not included in the statistics.
6. To export the performance report as a flat list with all levels to a .csv file, follow the steps below:
a. Select the Regeneration tab.
b. Click Flat List.
c. Click 
to show all levels of the flat list.
to show all levels of the flat list.d. Click Export. The Save dialog box opens.
7. You can browse to a different location to save the file.
8. Accept the file name or type a new name.
9. Click OK.
Note how information is updated in the Performance Report dialog box:
• After you click Compute, the regeneration time values remain in the Performance Report table until the next time you click Compute and perform the entire compute operation. This is true even if you closed the Performance Report dialog box and then opened it again.
• When you stop the compute operation in the process, the regeneration time values in the Performance Report table may be incorrect. Some of the values may be from the current compute operation and some may be missing or outdated.
Known Limitations
Below is a list of known limitations:
• Regeneration times are system dependent and will vary depending on other running processes.
• Multiple occurrences of the same component are all added to the respective assembly total. This can give an inaccurate result for the regeneration report of that assembly.
• Simplified representations are not fully supported, external simplified representations are not supported.
• Mechanism assemblies regenerate the first time you click Compute. to trigger their regeneration again, a change in the assembly is needed.
