# Rectangle

Interactive Use

Create Filter: With the cursor indicating that create mode is active ( ), left-click and drag to draw a rectangle to define the filter element extent. After use, the cursor will switch to reset mode.

Note

This actually specifies an extruded rectangle in three dimensions (in parallel mode) or a pyramid in space (in perspective mode). When first created, only the red rectangle indicating the drawn extent is shown. If the current view settings are moved, this extrusion is rendered transparently; the red rectangle indicates the position of the object on the original view plane. The vanishing point (in perspective mode) indicates the original eye position when the rectangle was drawn.

Reset Filter: Clear the existing filter element when the cursor indicates reset mode ( ) by holding the Shift key and left-clicking anywhere in the View pane. After use, the cursor will switch to indicate that create mode is active. Left-clicking without holding the Shift key will do nothing.

Attributes

Not: Invert the filter element’s selection.

Extent: If checked, only include the item if its entire extent fits within this filter element’s definition. If not checked, the item’s centroid is used to determine the location of the item and whether it is within the filter element’s definition.
