To filter clashes in the Clash Filter window choose jobs or specific clash groups on the left side. On the right side, select various criteria organized in columns such as storey, category, family, status, and their respective values. Selecting all clashes in one clash job and filtering certain levels makes it possible to detect collision density on the Level map for that storey or any other. If the filter option is enabled, the appropriate column in the clash detection list will have the symbol ‘*’ next to the column name. To remove the set filter, use the Reset Filter option.
