Suspending Automatic Rebuilds

While in Large Assembly Mode, you can defer the full update of assemblies until you are ready to rebuild the assembly. By deferring the update, you can make many changes, then rebuild the assembly once.

The assembly rebuilds automatically, if necessary, for internal updates and to protect the integrity of the model.

Use this option only when necessary. Rebuild errors created while this option is active do not become apparent until this option is deactivated or you manually rebuild. Determining the cause of the errors can be difficult after you deactivate the option and rebuild the assembly.

To defer the full update of assemblies:

Click Tools > Options > System Options > Assemblies and under When Large Assembly Mode is active, select Suspend automatic rebuild.

If you are editing either a Mate or items above Mates in the FeatureManager design tree and Suspend automatic rebuild is selected, items after the Mate folder are not automatically rebuilt.

If you create or edit an assembly feature with this option enabled, the assembly is updated until you finish editing the feature.

In an active assembly, operations for the center of mass linked to mass properties are updated only when they take 0.5 seconds or less. If the update takes more than 0.5 seconds, the center of mass is marked with (rebuild icon), and is not updated until you initiate a rebuild manually.
To manually update when in Suspend automatic rebuild mode, click Rebuild on the Standard toolbar.
See Large Assembly Mode for information about opening an assembly in Large Assembly Mode.
