    Both in the part and assembly environment, there is “Rebuild all” functionality available – but what does it do exactly and when is it needed?


    As described in the Inventor Help documentation, “Rebuild all” is used to ensure edits to all geometry is reflected in the model. The “update” command is meant to regenerate only geometry that has significant edits in memory, so “rebuild all” would regenerate the entire part file regardless. Within assemblies, this command regenerates assembly constraints, assembly sketches and adaptive parts.

    Given this information, when should this be used? Personally, I see this as one of the steps in troubleshooting issues with an Inventor model. If a model behaves as expected, there is no real benefit in regularly running a rebuild command. If there are any inconsistencies that can’t be otherwise explained, rebuilding the model could help. Even if it doesn’t end up fixing the problem, some errors could be flagged during the update which can help identify the cause.
