Selection Functions

A group of objects selected together, either by point selection or area selection, is referred as a selected set. By using selection functions, you can do the following:

Point at specific objects to be selected
Select all objects within a specified area
Select all objects in a specified cellview

You can select objects individually (point selection) or in groups (area selection) and add them to other selected groups of objects. You can subtract objects from a selected set (sub mode) or define certain objects to be unselectable (selection filter).

There are four categories of selection functions, as describes in the following table. The table lists the functions available at the SKILL level for creating, maintaining, and accessing selected sets.
