Performance Evaluation - Rebuild Performance

Rebuild Performance provides information about rebuilding an assembly.

   
Rebuild Data Unavailable Runs diagnostic tests on data from the most recent rebuild of the model. If the model has not been rebuilt in the current version of SOLIDWORKS, rebuild data is not available and some tests cannot be performed.

To rebuild the model:

Click Rebuild (Standard toolbar) or Edit > Rebuild or press Ctrl+B.
Rebuild Report
Reports the rebuild time for the total assembly. The report shows the time taken to rebuild significant components and features. Minor items are omitted. Complex relationships may cause some items to be visited twice.

Rebuild the assembly during the current session of SOLIDWORKS before generating the report.

The report is not available when the assembly rebuild time is less than 10ms.
Mates Checks the number of mates that are evaluated when the assembly rebuilds and the amount of time taken to evaluate those mates.
Certain mating conditions can result in slower rebuild times. If mates rebuild slowly, Performance Evaluation reports any mates that reference:
Assembly features Mates that reference assembly features rebuild slowly compared to mates that reference component geometry.
Patterned components Mates that reference instances of components that are generated by a component pattern rebuild slowly compared to mates that reference nonpatterned components.
Although the conditions identified by Performance Evaluation can degrade assembly performance, they are not errors. Weigh the Performance Evaluation recommendations against your design intent. In some cases, implementing the recommendation can improve assembly performance, but might compromise your design intent.
In the Mates dialog box, you can select a mate under Name to highlight the mate in the graphics area.
In-Context Part Performance Reports when in-context relationships involving relatively large parts contribute a significant percentage to the assembly rebuild time.

When an assembly is rebuilt, all in-context relationships established at the top level of the assembly are re-evaluated. First, the location of the driving component is determined by evaluating its mates and sometimes rebuilding the driving component. Then, the driven component is rebuilt. If the driven component is a complex part with many features, rebuilding the component can take a significant amount of time.

  • If you make changes that require the driven component to be resolved, then increased rebuild time is unavoidable.
  • If you work on components that are not related to the driven component, you can improve the rebuild performance of the assembly by suppressing the driven component.
In the In-Context Part Performance dialog box, you can:
  • Select one or more components in the list to highlight in the graphics area.
  • Click Isolate Components to display only the selected components in the graphics area. Click Exit Isolate (Isolate pop-up toolbar) to return to the list.
In-Context Relationship Performance Reports when components are rebuilt multiple times when the assembly is rebuilt.

In the In-Context Relationship Performance dialog box, you can:

  • Select a component and click Fix It. The update order of the assembly changes to reduce the number of times the component rebuilds.
In-Context Relationship Conflict Reports if a subassembly contains a single-configuration component that is driven by an in-context relationship to a multiple-configuration component. The result can be conflicts when rebuilding the assembly.

The in-context relationships can arise from equations or external references.

In the In-Context Relationship Conflict dialog box, you can:
  • Select a component and click Fix It. To resolve the conflict, a derived configuration is added to the selected component.
Assembly Rebuild Report Reports on the last assembly rebuild and shows the time taken to rebuild for significant components and features.
