In this sample file there is 3 configurations presenting 3 different configuration states:

Configuration A shows the icon Rebuild on Save Mark: This configuration will be fully generated when you save the document.
Configuration B shows the icon Out-of-date: This configuration is out-of-date or does not exist.
Configuration C shows the icon Up-to-date: This configuration is fully generated. This is always true for the active configuration.

The active configuration is highlighted in color, while the others are greyed out. Only 1 configuration can be active at a time. An active configuration must have one of the following statuses: Rebuild on Save Mark, Up-To-Date or Display Data Mark.

Important : DATAKIT SOLIDWORKS reader only reads 3d geometry from configurations marked as Up-to-date or Rebuild on the mark (configuration A and C here). For others Dtk_API::ReadComponent will return the error status dtkSw3dReadErrorMissingConfiguration (10001)

Only SOLIDWORKS itself can generate or rebuild configurations. If needed, you can manually add the Rebuild on Save Mark for all required configurations within SOLIDWORKS. Alternatively, you can use the SolidWorks Task Scheduler software to update your file by enabling the option Activate all configurations before saving.
