Following 3D Model Changes

When the 3D model has been substantially updated, the clash details remain in the Clash Manager database (not the 3D model database) even though the item(s) they refer to have been removed. In these circumstances, the particular clash details continue to be reported until all Clash Sets containing the detail have been rerun.

These clash details, including their comments, can be removed from the Clash Manager database by using the Delete all Unreferenced Groups and Elements and Comments functionality available from the Clash Manager Configuration window. Refer to Delete unreferenced data for further information.

This process removes historical data and consequently the original comments will have been lost, if the clash re-appears.
