Select Types

The selection type determines how any shape (point, line, or polygon) in a layer is selected. The selection types can be found in the Map menu or on the Map screen in the mapping toolbar.

• Select Objects- When this option is used, entire objects will be selected by any of the Selection Tools. For example if the Select Rectangle tool is selected and a selection box that crosses the edge of a polygon in a layer is drawn, the whole polygon will be selected not just the intersected area.

• Select Intersection- When this option is used, only the intersected area of an object is selected. For example, if the Select Rectangle polygon is selected and a region is drawn across a quarter of a line segment, then only that length of the line that fell in the selection area will be selected.
