Range

A command that does not have a range will operate on all possible target objects of the given command (e.g., zones, grid points, structural elements, etc.). A range, when applied to a command, provides the means to restrict the operation of the command to a subset of target objects. The subset is defined by range elements, which are keywords + values following the range keyword in a command. The term range phrase refers to the combination of the range keyword and one or more range elements that follow. The range phrase, when used, must always appear at the end of the command. The reference list of range elements can be accessed by clicking any range link throughout the documentation.

The range logic is best understood as a ref-command construct <flac3dcommandconstructs>- Common problem. That said, there is a model range command. The purpose of this command is to create or delete a named, user-specified set of range elements. However, the resulting set (the “named range”) is not applied to anything until it is utilized as a range.named-range element within a range.

Many commands accept a range phrase. A command signature that uses the range logic will always show the range phrase (<range>) as a final parameter (most often in angle brackets to indicate it is optional). For example:

zone apply keyword ... <range>

Note

Unless a range phrase is used on a command, the action of any command in will be applied to all possible target objects of the command.
