How to control when updates are applied to files you are working on
Update incorporates changes to parts or assembly components that are held in memory from the current editing session. The graphics window and browser update to show the changes. Update changes to indicate whether an assembly is fully up to date.
When significant changes have been made to a part file or assembly component (for example, editing a part in the assembly, placing a constraint, or editing a constraint), Global Update is the default choice.
You can trigger Update automatically or set an option to defer updates while you continue to work. When deferring updates, part positions will not change until you use the Update command.
To defer updates:
To manually apply edits to a part file or to one or all components of the current assembly:
Click Global Update when one or more components have significant changes. All components, including the top-level assembly, update.
Click Update to regenerate only the active part or subassembly and its dependent children.
The Update command dims to show the file is fully up-to-date.
