Select Method Parametersĭetermines the selection mode to be used. AutoCAD provides the following AcSelect enum constants for use with this parameter, as shown in Table 12-3. The Select method has several modes of operation specified by the Mode parameter. It allows you to select the previous selection set, the last visible entity, everything in the current space, or rectangular region. The Select method (see Table 12-2 for parameter details) is the basic way to add entities to SelectionSet objects.

There are SelectXXX methods for obtaining entities by specific point, by window, by arbitrary fence or polygon, by dynamic user selection, and by filtering the entities using specific criteria.

A SelectionSet is populated either by adding an array of objects, which I describe how to do later in this chapter, or by using one of the SelectXXX methods I describe in this section. Newly created SelectionSet objects are empty.
