Allows you to specify piping custom instrument that you want to use from the catalog.
Instruments
Specifies the piping custom instrument that you want to place. The default option is More. Upon selection, the list is saved and displays the five most recently selected custom instruments, so that you need not browse the catalog and re-navigate. Incompatible components are not displayed in the recently placed component list. For example, an Annubar Type is not shown in the recently placed component list when you are placing a component on a pipe straight feature.
Selecting More displays the Select Instrument Dialog.
