Filter Combinations

Source file: filter-combinations.htm

Most of the filtering tools allow you to combine previous filter results using the following options:

• And makes a point visible only if the point is visible after applying the most recent filter and the new filter determines the point will be visible.
• Or sets a point visible only if either the point is visible after applying the most recent filter or the new filter determines the point will be visible.
• Replace ignores any point filtering currently applied to the scan. The outcome will be a result of the new filter only.

Note:  Filter combinations with Select by Attribute (see Select by Attributes), will ignore points that aren’t visible.

These three options are illustrated below. The scan has been filtered by range (see Range). This scan is then filtered by a bounding box extent (see Polygon). Shown are the three different regions that result from each of the Filter combination options.

Note:  When items in a scan are filtered, they still exist in the database. They can be redisplayed by using the Show All option.
